Question

Which is a solution to the equation (10–5y) = 20?​

Answer 1

Answer: y = -2

Explanation:

10 - 5y = 20

Add 5y to both sides

10 = 5y + 20

Subtract 20 from both sides

-10 = 5y

Divide both sides by 5

y = -2

Answer 2

y = -2

Explanation:

10 -5y = 20 { subtract 10 from both sides}

-5y = 20 - 10

-5y = 10 {Divide both sides by (-5) }

y = 10/-5

y = -2
