You can put this solution on YOUR website!
Use substitution:
\n" ); document.write( "Since we know what x=, we can use this information to rewrite the following:
\n" ); document.write( "3(X) + 2Y = 8\r
\n" ); document.write( "\n" ); document.write( "3(3y+10) + 2Y = 8\r
\n" ); document.write( "\n" ); document.write( "clear the parentheses:
\n" ); document.write( "9y+30+2y=8\r
\n" ); document.write( "\n" ); document.write( "Consolidate like terms
\n" ); document.write( "11y+30=8\r
\n" ); document.write( "\n" ); document.write( "Subtract 30 from both sides:
\n" ); document.write( "11y=-22\r
\n" ); document.write( "\n" ); document.write( "Divide both sides by 11
\n" ); document.write( "y=-2\r
\n" ); document.write( "\n" ); document.write( "Substitute y back into either of your equations to find x:
\n" ); document.write( "3x+2(-2)=8
\n" ); document.write( "3x+-4=8
\n" ); document.write( "3x=12
\n" ); document.write( "x=4\r
\n" ); document.write( "\n" ); document.write( "Check with your other equation:
\n" ); document.write( "4=3(-2)+10
\n" ); document.write( "4=-6+10
\n" ); document.write( "4=4
\n" ); document.write( "True statement, so the solution set is (4,-2)
\n" ); document.write( " \n" ); document.write( "
\n" );
