Question

Solve each equation for y:

y^2 -1=80
(y-4) divided by 4=1
10-63 divided by y=1

They are each different numbers
Hint- y is less then 10 for all of them

Answer 1

Solve each equation for y:y^2 -1=80(y-4) divided by 4=110-63 divided by y=1

Explanation:

Answer 2

Explanation:

`{y}^(2) - 1 = 80`

`{y}^(2) = 81`

`y = ±9`

`(y - 4)/(4) = 1`

`y - 4 = 4`

`y = 8`

`(10 - 63)/(y) = 1`

`10 - 63 = y`

`- 53 = y`
