Question

Which of the following expressions is equal to "x + 5 = 10"?

a) x = 15
b) x = 5
c) x = 10
d) x = -5
e) x = 6

Answer 1

To solve the equation x + 5 = 10 for x, subtract 5 from both sides to get x = 10 - 5, which simplifies to x = 5. The correct answer is b) x = 5.

Step-by-step explanation:

The question asks us to solve for x in the equation x + 5 = 10. To solve for x, we need to isolate the variable on one side of the equation. We do this by subtracting 5 from both sides of the equation, which gives us:

x + 5 - 5 = 10 - 5

So, x = 10 - 5.

x = 5

Therefore, the correct answer is b) x = 5.
