One x- value of the solution is : -2 or -8
<h3>What is an equation?</h3>
An Equation is an algebraic statement that shows that two quantities are equal.
Analysis:
for one x-value of a solution, f(x) = g(x)
+ 7x -24 = -3x - 40
+7x +3x -24 +40 = 0
+ 10x +16 = 0
+8x +2x +16 = 0
x(x+8) +2(x+8) = 0
(x+2)(x+8) = 0
x = -2 or -8
In conclusion, the values of x are -2 or -8
