3х+8х=132

To solve the equation 3х + 8х = 132, we need to combine like terms on the left side of the equation. First, we add the coefficients of the like terms:

3х + 8х = 11х

So the equation becomes:

11х = 132

Next, we want to isolate х by dividing both sides of the equation by 11:

(11х)/11 = 132/11

Simplifying, we find:

х = 12

Therefore, the solution to the equation 3х + 8х = 132 is х = 12.
