What is x + 3 = 5?

5-3=2

the answer would be 2

Move all terms containing x to the left, all other terms to the right.

Add '-3' to each side of the equation.

3 + - 3 + x = 5 + - 3

Combine like terms: 3 + - 3 = 0

0 + x = 5 + - 3

x = 5 + - 3

Combine like terms: 5 + - 3 = 2

x = 2

Simplifying

x = 2
