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

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
