Solve for x and y by elimination or substitution\r
\n" ); document.write( "\n" ); document.write( "\"%28x-2%29%2F3+%2B+%28y%2B1%29%2F5+=2\"\r
\n" ); document.write( "\n" ); document.write( "multiply equation by 15
\n" ); document.write( "5(x-2)+3(y+1) = 30
\n" ); document.write( "5x-10+3y+3=30
\n" ); document.write( "5x+3y=37................................(1)\r
\n" ); document.write( "\n" ); document.write( "\"%28x%2B2%29%2F7+-+%28y%2B5%29%2F3+=-2\"\r
\n" ); document.write( "\n" ); document.write( "multiply equation by 21 (7*3)\r
\n" ); document.write( "\n" ); document.write( "3(x+2)-7(y+5)=-42\r
\n" ); document.write( "\n" ); document.write( "3x+6-7y-35=-42
\n" ); document.write( "3x-7y=-13..................................(2)\r
\n" ); document.write( "\n" ); document.write( "5 x + 3 y = 37 .............1
\n" ); document.write( "Total value
\n" ); document.write( "3 x -7 y = -13 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 7
\n" ); document.write( "Multiply (2) by 3
\n" ); document.write( "35 x 21 y = 259

\n" ); document.write( "/ 44
\n" ); document.write( "x = 5
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "5 x + 3 y = 37
\n" ); document.write( "25 + 3 y = 37
