Question

2(5y-3)-4=20 what is the answer​

Answer 1

Step-by-step explanation:

$10y - 6 - 4 = 20 \\ 10y - 10 = 20 \\ 10y = 20 + 10 \\ 10y = 30 \\ y = \frac{30}{10} \\ y = 3$

Answer 2

Step-by-step explanation:

2(5y - 3) - 4 = 20

10y - 6 - 4 = 20

10y - 10 = 20

10y = 20 + 10

10y = 30

y = 30/10

y = 3
