Question

How do you solve `56+ x = 45- 58`?

Answer 1

`x=-69`

Explanation:

Given
`color(white)("XXX")56+x=45-58`

Performing the indicated arithmetic on the Right Side
`color(white)("XXX")56+x=-13`

Since we can add or subtract the same amount to both sides of an equation,
we can subtract `56` from both sides:
`color(white)("XXX")x=-69`
