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
\(\frac{w}{3}-15=12\)
add 15 to both sides
\(\frac{w}{3}+15-15=12+15\)
\(\frac{w}{3}+0=27\)
\(\frac{w}{3}=27\)
tiemes both sides by 3/1
\(\frac{3w}{3}=27*3\)
\((\frac{3}{3})w=81\)
\(1w=81\)
\(w=81\)
