3х+8х=132

To solve the equation 3x + 8x = 132, we need to combine like terms on the left side of the equation.

First, add the coefficients of the x terms:

3x + 8x = 11x

So the equation becomes:

11x = 132

To find the value of x, divide both sides of the equation by 11:

11x/11 = 132/11

Simplifying, we get:

x = 12

Therefore, the value of x that satisfies the equation is x = 12.
