ANSWER:
Part A: 1 solution
Part B: x = 2
Explanation:
We have the following equation:
Part A:
We can determine the number of solutions of the equation if we know its degree, that is, the maximum exponent of the unknown, in this case, x.
We can see that it is of degree 1, so it has only one solution
Part B:
We solve the equation by solving for x, like this:
The solution of the equation is x = 2
