17. Solve for x in the equation x - 4 =

7.
A. x = 11
B. x = 3
C. x = -3
D. X = 28

Answer 1

Answer: A. x = 11.

Explanation:

To solve for x in the equation x - 4 = 7, we need to isolate x on one side of the equation.

To do this, we can add 4 to both sides of the equation to cancel out the -4 on the left side:

x - 4 + 4 = 7 + 4

This simplifies to:

x = 11

Therefore, the solution to the equation x - 4 = 7 is x = 11.

So, the correct answer is A. x = 11.
