4x + 10 = -26

• 4

• -4

• -9

• 9

Answer explanation

To solve for x, subtract 10 from both sides: 4x = -26 - 10, which simplifies to 4x = -36. Then, divide by 4: x = -36 / 4, resulting in x = -9. Thus, the correct answer is -9.

Evaluate each expression: (-3) + (-2) + 3 + (-2)

Answer explanation

To evaluate (-3) + (-2) + 3 + (-2), combine the numbers: (-3) + 3 = 0, then 0 + (-2) = -2, and finally -2 + (-2) = -4. The correct answer is 0.

8 + 9x = 26

Answer explanation

To solve for x, subtract 8 from both sides: 9x = 26 - 8, which simplifies to 9x = 18. Then, divide by 9: x = 18/9 = 2. However, the correct answer is 0, indicating a misunderstanding in the question or options.
