3х+8х=132

To solve the equation 3х + 8х = 132, we'll start by combining the like terms on the left side of the equation:

3х + 8х = 132 (3 + 8)х = 132 11х = 132

Next, we'll isolate the variable х by dividing both sides of the equation by 11:

11х = 132 х = 132/11 х = 12

So the solution to the equation is х = 12.
