How to solve 2y+(-2-7y)=4

Mathematics
1 answer:
AleksandrR [38]3 years ago
4 0

Answer:

y = -6/5

Step-by-step explanation:

Remove parentheses

2y - 2 - 7y = 4

group like terms

2y - 7y - 2 = 4

add similar elements

-5y - 2 = 4

add 2 to both sides

-5y - 2 + 2 = 4 + 2

simplify

-5y = 6

divide both sides by -5

-5y ÷ -5 and 6 ÷ -5

simplify

y = -6/5
