To determine which equation is true when substituting \( x = 4 \), we need to evaluate each option. For option A, substituting yields \( 3(4) + 4 = 12 + 4 = 16 \), which is not equal to 8. In option C, substituting gives \( 2(4) + 8 = 8 + 8 = 16 \), not equal to 40, confirming that none of the given equations hold true when \( x = 4 \).

are you sure?

Let me reevaluate each equation for \( x = 4 \):

A. \( 3x + 4 = 8 \):
Substituting gives \( 3(4) + 4 = 12 + 4 = 16 \), which is not equal to 8.

B. \( 5x - 2 = 18 \):
Substituting gives \( 5(4) - 2 = 20 - 2 = 18 \), which is true.

C. \( 2x + 8 = 40 \):
Substituting gives \( 2(4) + 8 = 8 + 8 = 16 \), which is not equal to 40.

D. \( 4x + 4 = 12 \):
Substituting gives \( 4(4) + 4 = 16 + 4 = 20 \), which is not equal to 12.

Therefore, the correct equation when \( x = 4 \) is indeed option B. Thank you for your patience!
