Question

g

Answer 1

8x+8=4x+28 because they are both equal to each other
-4x -8 -4x -8
------------
4x=20
x=5

Answer 2

now we know the variable equals 5, and we plug it in to the equations

Answer 3

8(5)+8
40+8
=48

4(5)=28
20+28
=48

Answer 4

multiplied by two =96

Answer 5

That's not correct @Jamierox4ev3r

This is the same principle as your last question - the angles are co-interior angles and add up to 180:

8x+8 + 4x+28 = 180

First group the terms together:

8x + 4x + 8 + 28 = 180
