\n" ); document.write( "You are going to want to take the first equation times -2
\n" ); document.write( "Then take your second equation times 5
\n" ); document.write( "The reason you are doing this is because when you take -2 times 5 you will get -10 and then when you take 5 times 2 in your second equation you will get a positive 10 which will make those cancel out.(you want to cancel out the x value)\r
\n" ); document.write( "\n" ); document.write( "-2(5x+3y=-11)
\n" ); document.write( "5(2x+4y=-10)
\n" ); document.write( "after multiplying it should look like this:
\n" ); document.write( "-10x+-6y=22
\n" ); document.write( "10x+20y=-50
\n" ); document.write( "Then you simply add the two equations together
\n" ); document.write( "0x+14y=-28
\n" ); document.write( "solve for y
\n" ); document.write( "y=-2
\n" ); document.write( "Then pick one of your original equations and plug in your known y value
\n" ); document.write( "5x+3(-2)=-11
\n" ); document.write( "5x+-6=-11
\n" ); document.write( "5x=-5
\n" ); document.write( "x=-1
\n" ); document.write( "You can then check the x and y value in the other equation to make sure it is correct.
\n" ); document.write( "2(-1)+4(-2)=-10
\n" ); document.write( "and both of the values worked which means we got the right answer! :)
