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

Respuesta :

Step-by-step explanation:

[tex] {y}^{2} - 1 = 80[/tex]

[tex] {y}^{2} = 81[/tex]

[tex]y = ±9[/tex]

[tex] \frac{y - 4}{4} = 1[/tex]

[tex]y - 4 = 4[/tex]

[tex]y = 8[/tex]

[tex] \frac{10 - 63}{y} = 1[/tex]

[tex]10 - 63 = y[/tex]

[tex] - 53 = y[/tex]

Answer:

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