Answer:

5

Step-by-step explanation:

Combine like terms:

23x and 6x are like terms so we add them together. 23x + 6x is 29x

Now you have the equation, 140 = 29x - 5.

Add both sides by 5. 140 + 5 = 145; -5 + 5 (cancels out)

Now your left with,  145 = 29x

Divide both sides by 29. 29x divided by 29 = x; 145 divided by 29 = 5.

Therefore, x = 5.
