If you want to solve for w:
w/18= 3
multiply both sides by 18
(w/18)(18)= (3)(18)
18 "cancels out" on the left side
w= 54
CHECK
54/18= 3
3= 3
ANSWER: w= 54

Answer:
x=10
Step-by-step explanation:
Rearrange to get p on one side
2.5=0.4p-0.15p
2.5=0.25p
Divide both sides by 0.25
2.5/0.25=x
x=10
By subtracting x from 2x you’ll get the answer: 4x^2+x+2 I hope that helps!!
