3х+8х=132

To solve this equation, we need to combine like terms on the left side:

3x + 8x = 132

Combining "3x" and "8x" gives us:

11x = 132

Now, we need to isolate x by dividing both sides of the equation by 11:

11x/11 = 132/11

Simplifying, we get:

x = 12

Therefore, the solution to the equation is x = 12.
