Answer:
w=20.1
Step-by-step explanation:
well first you would need to subtract 9 from both sides.
10w=201
next you would have to divide the 10 from both sides, since the 10 was being multiplied, inverse operation.
and there you have it.
21.9 or 21 9/10
10x-9=210
10x=210+9
x=219/10
x=21.9 or 21 9/10
Hope this helps!!
