Question

How do you solve `112 = -u + 179`?

Answer 1

See a solution process below:

Explanation:

Subtract `color(red)(112)` and add `color(blue)(u)` to each side of the equation to solve for `u` while keeping the equation balanced:

`color(blue)(u) + 112 - color(red)(112) = color(blue)(u) - u + 179 - color(red)(112)`

`u + 0 = 0 + 67`

`u = 67`

Answer 2

`u=67`

Explanation:

`"isolate - u by subtracting 179 from both sides of the equation"`

`112-179=-ucancel(+179)cancel(-179)`

`rArr-67=-u`

`"multiply both sides by "-1`

`-1xx-67=-1xx-u`

`rArr67=u" or "u=67`
