4(x+x+7)-2x+8-4
Substitute x with 1
4(1+1+7)-2(1)+8-4
=4(2+7)-2+4
=4(9)-2+4
=36-2+4
=34+4
=38

4(x+x+7)-2x+8-4
Substitute x with 2
4(2+2+7)-2(2)+8-4
=4(4+7)-4+4
=4(11)
=44. Hope it help!

Solve this linear system by graphing <br> x-y=6 <br> 2x=12+2y

lys-0071 [83]

You need to isolate the variables. For the first equation add x to both sides, which leaves you with y.

For the second equation, divide each side by 2 leaving you with
x= 6+y. Subtract y from each side. Subtract x from both sides. Now you have y= x + 6.

Now graph those equations.
