Answer:
[tex]w=60[/tex]
see the explanation
Step-by-step explanation:
we have
[tex]\frac{1}{2}w-12=18[/tex]
Solve for w
That means---> Isolate the variable w
step 1
Adds 12 both sides
[tex]\frac{1}{2}w-12+12=18+12[/tex]
[tex]\frac{1}{2}w=30[/tex]
step 2
Multiply by 2 both sides
[tex](2)\frac{1}{2}w=(2)30[/tex]
[tex]w=60[/tex]
