See a solution process below:

Explanation:

Step 1) Subtract color(red)(5) from each side of the equation to isolate the x term while keeping the equation balanced:

-color(red)(5) - 51 = -color(red)(5) + 5 + 8x

-56 = 0 + 8x

-56 = 8x

Step 2) Divide each side of the equation by color(red)(8) to solve for x while keeping the equation balanced:

-56/color(red)(8) = (8x)/color(red)(8)

-7 = (color(red)(cancel(color(black)(8)))x)/cancel(color(red)(8))

-7 = x

x = -7
