Question

Is anyone good at this math

Answer 1

x = 3

Explanation:

4 + x = 7

x + 4 - 4 = 7-4 = 3

x = 3

To solve for x, subtract 4 from both side of the equation. This leaves x by itself on the left side of the equation. Next subtract 4 from 7 to get the solution, x = 3.

Answer 2

x = 3

Explanation:

4 + x = 7 Subtract 4 from both sides of the equation

4 - 4 - x = 7 - 4 Simplify

x = 3 X equals 3
