Final answer:

The value of x that makes the equation 2x + 3 = x - 4 true is -7. This is found by subtracting x and 3 from both sides of the equation.

Step-by-step explanation:

The equation given is 2x + 3 = x - 4. To find the value of x that makes this equation true, we will need to solve for x.

Step 1: Subtract x from both sides of the equation to get x isolated on one side:

2x + 3 - x = x - 4 - x

x + 3 = -4

Step 2: Subtract 3 from both sides of the equation to solve for x:

x + 3 - 3 = -4 - 3

x = -7

Therefore, the value of x that makes the equation true is -7.
