If 4x = 8x - 1 then 4x must be equivalent to 1. So that means x is .25 or 1/4.
Hope this helps!
(I assumed your trying to solve for x, please word the question better next time)
Jessica solved for the correct value of a, but Sally's review was incorrect.
Year 3 = 2s
Year 2 = 3 + x
Year 1 = x
s = second year
x = first year
2s = 26
s = 13
The second year they made 13 million
13 - 3 = 10
x = 10
They made 10 million the first year.
