Final answer:
To find the value of x, we equate the expressions for A and B and solve the resulting equation for x. The value of x is -6.
Step-by-step explanation:
To find the value of x, we need to equate the expressions for A and B. We have A = 8x + 2 and B = 9x + 8.
Setting A = B gives us:
8x + 2 = 9x + 8
Subtracting 8x from both sides:
2 = x + 8
Subtracting 8 from both sides:
-6 = x
Therefore, the value of x is -6.
