3х+8х=132

To solve the equation 3x + 8x = 132, we can combine the like terms on the left side of the equation:

3x + 8x = 11x

So the equation becomes 11x = 132.

To find the value of x, we can isolate x by dividing both sides of the equation by 11:

(11x) / 11 = 132 / 11

x = 12

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