Question

Need help I'm getting it wrong I don't understand

Answer 1

w/3-15=12
remember, you can do ANYTHING to an equaiton as long as you do it to both sides
get w by itself


`(w)/(3)-15=12`
add 15 to both sides

`(w)/(3)+15-15=12+15`

`(w)/(3)+0=27`

`(w)/(3)=27`
tiemes both sides by 3/1

`(3w)/(3)=27*3`

`((3)/(3))w=81`

`1w=81`

`w=81`
