Question

What is 10 + x = 23?

Answer 1

13

Explanation:

Assuming we are trying to find x, we know that x and 10 together are equal to 23, so if we subtract 10 from both sides to have x by itself on one side,

`10+x=23\\10-10+x=23-10\\x=13`

and its value on the other.

Answer 2

x = 13

Explanation:

This is a simple algebraic problem. Since x must be left by itself in order to solve, we subtract 10 on both sides, giving us the final answer of x = 13.
