4) Solve for x using y = x - 4.
x = y + 4
Now plug x in to y = 6x - 10.
y = 6(y + 4) - 10
y = 6y + 24 - 10
y = 6y + 14
-5y = 14
y = -14/5
Plug y back in to x = y + 4.
x = -14/5 + 4
x = 1.2
(6/5, -14/5)

5) Make the expressions equal to each other.
2x + 3 = 3x - 6
9 = x
x = 9

Answer:

80*

75*

120*

Step-by-step explanation:

both angle 1 and 2 for the first image have the same value as the other angle of 80* because it is a set of parallel lines and one line going through it.

1 on the next set of images is 75* because is is an alternate exterior angle.

2 of the last set of images is 120* because it is same side interior angles.
