Help me plz I have headache and cant think

Answer: y=9

Step-by-step explanation:

Simplifying

7y = 3y + 36

Reorder the terms:

7y = 36 + 3y

Solving

7y = 36 + 3y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-3y' to each side of the equation.

7y + -3y = 36 + 3y + -3y

Combine like terms: 7y + -3y = 4y

4y = 36 + 3y + -3y

Combine like terms: 3y + -3y = 0

4y = 36 + 0

4y = 36

Divide each side by '4'.

y = 9

Simplifying

y = 9

Find the value of the variable.<br> All answers

First one.

Since the two angles are congruent through vertical angles theorem,

5x = 6x - 8

5x - 6x = -8

-x = -8

x = 8

Second one.

Use the 180° rule.

(8x - 2) + (2x + 2) = 180

8x - 2 + 2x + 2 = 180

8x + 2x + 2 - 2 = 180

10x = 180

x = 180 / 10

x = 18

Third one.

Vertical angle theorem.

7x = 5x + 40

7x - 5x = 40

2x = 40

x = 40 / 2

x = 20
