Answer: 5

Step-by-step explanation:Solving for variable 'x'.

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

Add '-2x' to each side of the equation.

7 + 8x + -2x = 37 + 2x + -2x

Combine like terms: 8x + -2x = 6x

7 + 6x = 37 + 2x + -2x

Combine like terms: 2x + -2x = 0

7 + 6x = 37 + 0

7 + 6x = 37

Add '-7' to each side of the equation.

7 + -7 + 6x = 37 + -7

Combine like terms: 7 + -7 = 0

0 + 6x = 37 + -7

6x = 37 + -7

Combine like terms: 37 + -7 = 30

6x = 30

Divide each side by '6'.

x = 5

Simplifying

x = 5

8x + 7 = 2x + 37

1. subtract 7 from the 7 on the left and 37 on the right

8x+7 (-7)= 2x + 37 (-7)

8x =2x +30

2.subtract 2x from 2x on the right and 8x on the left

8x -2x = 2x -2x +30

6x= 30

3.divide 6 from each side

6x/6 = 30/6

6 divided by 6 cancels out

30 divided by 6 is 5

x = 5
