    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
