To solve the system of equations, we need to find the values of x that satisfy both equations f(x) = 2x^2 - 3x - 10 and g(x) = x + 20.

Setting the two equations equal to each other, we get:

2x^2 - 3x - 10 = x + 20

Simplifying and rearranging, we get:

2x^2 - 4x - 30 = 0

Dividing both sides by 2, we get:

x^2 - 2x - 15 = 0

Factoring the left-hand side, we get:

(x - 5)(x + 3) = 0

Therefore, the solutions to the system of equations are x = 5 and x = -3.

One x-value of a solution is x = -3. So the answer is (b) x = -3.
