Question: 1 / 400

If x + 3 = 10, what is the value of x?

x = 4

x = 5

x = 7

To find the value of x in the equation x + 3 = 10, we need to isolate x. This can be done by performing the same operation on both sides of the equation.

Start by subtracting 3 from both sides of the equation:

x + 3 - 3 = 10 - 3

This simplifies to:

x = 7

Thus, the value of x is 7. In this case, the equation is set up to solve for x, and understanding how to manipulate the equation is crucial for arriving at the correct solution. The other options do not satisfy the equation when substituted back, hence they are not valid answers.
