\n" ); document.write( "1) x+y=5
\n" ); document.write( " 3x-y=7
\n" ); document.write( "---------- Add
\n" ); document.write( "That method is elimination.
\n" ); document.write( "==================================
\n" ); document.write( "2) 2x+y=3
\n" ); document.write( " -2x+5y=-9
\n" ); document.write( "Same as #1
\n" ); document.write( "===============================
\n" ); document.write( "3) 3x+5y=0
\n" ); document.write( " 2x-5y=-25
\n" ); document.write( "Same as #1
\n" ); document.write( "================================
\n" ); document.write( "4) -4x-y=-6
\n" ); document.write( " 4x+3y=18
\n" ); document.write( "5) 2x-y=-5
\n" ); document.write( " -2x-5y=11
\n" ); document.write( "6) 8=4x-3y
\n" ); document.write( " 17=x+3y
\n" ); document.write( "7) -6=3x+y
\n" ); document.write( " 10=-5x-y
\n" ); document.write( "8) 3x+8y=-1
\n" ); document.write( " -3x+y=-17
\n" ); document.write( "4 thru 8 same as #1
\n" ); document.write( "================================
\n" ); document.write( "9) x+2y=15
\n" ); document.write( " 5x=2y+3 --> 5x-2y = 3
\n" ); document.write( "Then same as #1
\n" ); document.write( "==============================
\n" ); document.write( "10) 7x-y=12
\n" ); document.write( " -3y=7x+8
\n" ); document.write( "Rearrange, then ...
\n" ); document.write( "=========================
\n" ); document.write( "11) y=3x+13
\n" ); document.write( " 2x=y-9
\n" ); document.write( "You can do it like #1, elimination, or you can use substitution.
\n" ); document.write( "Since y is given in the 1st eqn, sub for it in the 2nd.
\n" ); document.write( "2x = y - 9
\n" ); document.write( "2x = 3x+13 - 9
\n" ); document.write( "Then solve for x, etc
\n" ); document.write( "=============================
\n" ); document.write( "12) 4x+12=-7y
\n" ); document.write( " -y+12=4x
\n" ); document.write( "Rearrange, then subtract.
\n" ); document.write( "===========================
\n" ); document.write( "13) 3x+2y=6
\n" ); document.write( " y=x+3
\n" ); document.write( "Sub for y in the 1st eqn
\n" ); document.write( "=========================
\n" ); document.write( "14) -x+4y=-4
\n" ); document.write( " y=x-1
\n" ); document.write( "Same as #13
\n" ); document.write( "====================
\n" ); document.write( "15) -300x-125y=1350
\n" ); document.write( " y+2=8
\n" ); document.write( "No x in the 2nd eqn --> y = 6
\n" ); document.write( "==============================
\n" ); document.write( "16) 2x-y=6
\n" ); document.write( " 1/6x-1/12y=1/2
\n" ); document.write( "Multiply eqn 2 by 12 to eliminate fractions.
\n" ); document.write( "Then the 2 equations are the same.
\n" ); document.write( "--> dependent, and infinite # of solutions.
\n" ); document.write( "================================
\n" ); document.write( "17)4x+4y=5
\n" ); document.write( " x-4y=-5/2
\n" ); document.write( "--------------- Add
\n" ); document.write( "===========================
\n" ); document.write( "18) -2x+y=-6
\n" ); document.write( " 6x-13y=-12
\n" ); document.write( "Multiply the 1st eqn by 3, then add
\n" ); document.write( "============================
\n" ); document.write( "19) 2(x+2y)=12 --> x + 2y = 6
\n" ); document.write( " -6x=5y-8
\n" ); document.write( "Solve eqn 1 for x, sub for x in eqn 2
\n" ); document.write( "===========================
\n" ); document.write( "*****************************************
\n" ); document.write( "Pick the best method for the rest.
