To solve the equation, let's combine like terms and isolate the variable x:

5x + 8 + x = 32

Combining like terms:

6x + 8 = 32

Next, let's isolate the variable x. We'll subtract 8 from both sides:

6x + 8 - 8 = 32 - 8

The 8s cancel out on the left side:

6x = 24

To get the value of x, we'll divide both sides of the equation by 6:

(6x)/6 = 24/6

Simplifying:

x = 4

To check if x = 4 is the correct solution, we substitute it back into the original equation and see if both sides of the equation are equal.

Original equation: 5x + 8 + x = 32

Substituting x = 4:

5(4) + 8 + 4 = 32

Simplifying:

20 + 8 + 4 = 32

32 = 32

Since both sides of the equation are equal, the solution x = 4 is correct.
