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

Step-by-step explanation:

We replace every x's on the equation

$y =\frac{5x - 4}{-4}$

For x = 1

$y_1 = \frac{5*1 - 4}{-4} = -1/4$

For x = 2

$y_2 = \frac{5*2 - 4}{-4} = -6/4 = -3/2$

For x = 3

$y_3 = \frac{5*3 - 4}{-4} = -11/4$
