Hello there!
Explanation:
↓↓↓↓↓↓↓↓↓↓↓
First you had to switch sides of the equation.
Then you had to cancel by the common factor of 2.
You had to multiply by 37 from both sides of the equation.
Simplify it should be the correct answer.

Answer:
19. x = 65
20. x = 12
21. x = 35, y = 85
Step-by-step explanation:
19. 2x -10 = 120
2x (-10 + 10) = (120 +10)
2x/2 = 130/2
x = 65
20. 2x + 4x + 108 = 180
6x + (108 - 108) = (180 - 108)
6x/6 = 72/6
x = 12
21. 2x + 25 = 3x - 10
2x + (25 - 25) = 3x (- 10 - 25)
(2x - 3x) = (3x - 3x) - 35
-x/-1 = -35/-1
x = 35
3x - 10 + y = 180
3(35) - 10 + y = 180
105 - 10 + y = 180
(95 - 95) + y = (180 - 95)
y = 85
I have attached an image of the process I used
Is there a picture?
So we can figure it out
