Answer:
x = 20
y = 100
Step-by-step explanation:
To figure out x do this.
3x + 2x = 7x - 40 (collect like terms)
5x = 7x -40 (subtract 7x on both sides)
-2x = -40 (divide by -2 on both sides)
x = 20
Plug in to get y
Since 7x - 40 and y are vertical they equal the same amount
7(20) - 40 = y (multiply 7 by 20)
140 - 40 = y (collect like terms)
100 = y

The middle right is 145-90, so 55°. I'm not sure about the others
<span>simplified would be

2(x + 3)+ 8 + 5(x - 2) + 4x + 3
= 2x + 6 + 8 +5x -10 + 4x +3
= (</span>2x + 5x +4x ) + (6 + 8 -10 + 3)
=11x + 7
