You can put this solution on YOUR website!
4x + 3y = 8
\n" ); document.write( "4x + 6y = 20
\n" ); document.write( "ssubtract the first equation from the second to get:
\n" ); document.write( "3y = 12
\n" ); document.write( "solve for y to get y = 4
\n" ); document.write( "sreplace y with 4 in the first equation to get:
\n" ); document.write( "4x + 12 = 8
\n" ); document.write( "subtract 12 from both sides of the equation to get:
\n" ); document.write( "4x =-4
\n" ); document.write( "solve for x to get:
\n" ); document.write( "x = -1
\n" ); document.write( "your values of x and y should be x = -1 and y = 4
\n" ); document.write( "replace x and y with that in both equations to get:
\n" ); document.write( "-4 + 12 = 8
\n" ); document.write( "-4 + 24 = 10
\n" ); document.write( "both equations are true, confirming the values of x and y are good.
\n" ); document.write( "your solution is that x = -1 and y = 4
\n" ); document.write( "if you graph both equations, the intersection of the straight lines will be at (-1,4) as shown below.\r
