3 (x+5) = -4+8 how many solutions does the following equation have

One solution

Step-by-step explanation:

3 (x+5) = (-4) + 8

3x+15=4

3x=-11

x=-11/3

Alternatively, you can see how many solutions a polynomial equation has based on their degree (the highest variable exponent), which in this case is 1, so it'd have no more than one solution.
