3х+8х=132

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

3x + 8x = 132 11x = 132

Now, we want to isolate x, so we need to get rid of the coefficient 11. We can do this by dividing both sides of the equation by 11:

11x/11 = 132/11 x = 12

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