Solve the linear equation:

x-y=7

0.5x+y=5

Add the equations.

x-y%2B0.5x%2By=7%2B5

1.5x=12

highlight%28x=8%29

Now use either equation to solve for y.

8-y=7

highlight%28y=1%29

x=8

y=1

hi,

6x times 4 is 24x and 5 times 4 is 20, so the answer is 24x+20.

hope this and for a little humor i am groot.
