Question

Joe won 75 pieces of gum playing hoops. After giving some away he only has 51 remaining. How many did he give away?

Answer 1

Answer:
`x=24`

Explanation:

We can solve this problem by solving for the variable
`x` in the equation
`75-x=51`. We do this by first isolating the term
`-x` with subtraction:

`75-x=51`

`-75`
`-75`

`-x=-24`

Then we multiply both sides by
`-1` so we can get the value of
`x`:

`-x`
`=`
`-24`

`*(-1)`
`*(-1)`

`x`
`=`
`24`
