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

svlad2 [7]
A: 6/8, 9/12, 12/16
b: 6/14, 9/21, 12/28
c: 6/9, 2/3, 4/6
d: 1/4, 2/8, 2/12

In order to find equivalent fractions for a fraction is multiply or divide the numerator and denominator by the same number.

For example, 3/4=6/8 because 3x2=6 and 4x2=8, 6/8.

Hope this helps!
