Answer:

7/6 (= 1 1/6)

Step-by-step explanation:

5(3-2y)+4y=8 (by PEDMAS, expand distribute parenthesis first)

3(5) -2y(5) + 4y = 8

15 - 10y + 4y = 8

15 - 6y = 8 (subtract 15 from both sides)

-6y = 8 - 15

-6y = -7 (divide both sides by -6)

y = -7 / -6 = 7/6 = 1 1/6

Answer:

y = 10.5

Step-by-step explanation:

5 x (3 - 2y) + 4y = 8

5 x (3 + -2y) + 4y = 8

15 + -10y + 4y = 8

15 + -6y = 8

(15/6) (-6y/+6)

2.5 Y

-Y + 2.5 = 8

10.5 - 2.5 = 8
