Question

Noah writes the equation 3(x+7)=57 to represent the situation. Use the distributive property to write this equation another way.

Answer 1

3x+21=57

Explanation:

When we use distributive property we do

`3*x` and
`3*7` which will like this when rewritten
`3x+21=57`

Check answer:

`3x+21=57\\-21=-21\\3x=36`
`(3x)/(3) =(36)/(3)`

x=12 3(12)+21=57

36+21=57
