Divide 840 by the answer from this equation (0.08 - 1), then you can solve for "y".
Good luck!

.08 y - y = 840
multiply both sides by 100 to get rid of decimal
8y - 100y = 84000
-92 y = 84000
divide both sides by -92
y = 84000 / -92
y = -913.043..

(.08-1)y = 840
-.92y = 840
Divide both sides by -.92
y=840/-.92
y=-913.04
Proof
(.08 X -913.04)-(-913.04) = -73.04 + 913.04 = 840

.08y-y=840... multiply both sides by 100
8y-100y=84000
-92y=84000
divide both sides by -92...
y=-913.04348 or 913.04
