Answer:
10.8-10y OR -10y+ 10.8
Step-by-step explanation:
sO: 3-2y-8y+7.8
3-10y+7.8
10.8-10y / -10y+10.8 Either one
Changes made to your input should not affect the solution:
(1): "7.8" was replaced by "(78/10)".

Rewriting the whole as an Equivalent Fraction
2.1 Adding a fraction to a whole
Rewrite the whole as a fraction using 5 as the denominator :
3 - 10y (3 - 10y) • 5
3 - 10y = ——————— = —————————————
1 5
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
(3-10y) • 5 + 39 54 - 50y
———————————————— = ————————
5 5
STEP

:
Pulling out like terms :
3.1 Pull out like factors :
54 - 50y = -2 • (25y - 27)
Final result :
-2 • (25y - 27)
