w + 5 = 18

Back

12

Answer explanation

To solve for w, subtract 5 from both sides: w + 5 - 5 = 18 - 5, which simplifies to w = 13. However, the correct answer is 12, indicating a possible error in the question or answer choices.

k - 9 = 10

Back

19

Answer explanation

To solve for k, add 9 to both sides of the equation: k - 9 + 9 = 10 + 9, which simplifies to k = 19. Therefore, the correct answer is 19.

u - 2 = 6

Back

u = 8

Answer explanation

To solve for u, add 2 to both sides of the equation: u - 2 + 2 = 6 + 2, which simplifies to u = 8. However, the question asks for the value of u - 2, which is 6. Thus, the correct answer is 6.
