If we multiply the top equation by -4 we can get rid of the x so:

-4x+20y=-12

4x-4y=12

Add these up

16y=0

Y=0

X=3

Help me write "5x-(x-18)= " in those things. 5(-7) &lt;---- (Something like that)<br> X = -7
anzhelika [568]

Answer:

This how you get x. First the way to find the answer is to first put 5x by itself by canceling it out and putting it on the other side of the = which will be

              5x-(x-18)=

          -5x            -5

Which then gets  you this

         -(x-18)=-5x

After that its

x-18=-5x

once you have this subtract x

x-18=-5x

-x     -x

-18=-6x

Then it leaves you the easy part of just dividing

-18/-6x=-6x/-6x

After dividing you get x to be 3

x=3

Once you have x=3  input that number into your equation and you get the answer.

Hope this helps
