Question

How do I solve 5x=-4y+4;x=1,2,3

Answer 1

x=1
5=-4y+4
4y=-1
y=-1/4

x=2
10=-4y+4
4y=-6
y=-3/2

x=3
15=-4y+4
4y=-11
y=-11/4

Answer 2

Answer:
`y_1 = -1/4\\y_2 = -3/2\\y_3 = -11/4`

Explanation:

We replace every x's on the equation

`y =(5x - 4)/(-4)\\`

For x = 1

`y_1 = (5*1 - 4)/(-4) = -1/4`

For x = 2

`y_2 = (5*2 - 4)/(-4) = -6/4 = -3/2`

For x = 3

`y_3 = (5*3 - 4)/(-4) = -11/4`
