See a solution process below:

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

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

$- 56 = 0 + 8 x$ $-56 = 0 + 8x$

$- 56 = 8 x$ $-56 = 8x$

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

$- \frac{56}{8} = \frac{8 x}{8}$ $-56/color(red)(8) = (8x)/color(red)(8)$

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

$-7 = x$

$x = -7$

How do you solve -51= 5+ 8x−51=5+8x-51= 5+ 8x?
