3х+8х=132

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

Combining 3x and 8x gives us 11x.

So, the equation becomes: 11x = 132.

To solve for x, divide both sides of the equation by 11:

(11x) / 11 = 132 / 11

Simplifying, we have:

x = 12.

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