Question

In 19= x + 10, what number do we need to move in order to solve for x?

Answer 1

You need to move number 10.

Explanation:

19 = x + 10

19 - 10 = x

X = 9

Answer 2

Equations

Given equation:

`\sf{19 = x + 10}`

In order to solve for x, move 10 to the left side by subtracting it.

`\sf{19 - 10 = x}` <- simplify

`\sf{9 = x}` <- this is our final answer

Therefore, x = 9.
