4.5w = 5.1w -30
4.5w - 5.1w = 5.1w - 5.1w -30 (subtracted 5.1w on both sides)
4.5w - 5.1w = -30 (next combine like terms)
-0.6w = -30 (next do the inverse operation of w)
w = -30 ÷ -0.6
w = 50 (it became positive cause minus and minus = positive)
so your final answer is: w = 50

Answer:
8
Step-by-step explanation:
let the number=x
8(x-2)=16(x-5)
divide by 8

x-2=2x-10
2x-x=-2+10
x=8
