Answer:

first we get y on one side by itself.

4x+5y=5

we'll move x to the other side.

4x-4x+5y=5-4x

simplify.

5y=5-4x

now we get rid of the coefficient on y.

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

simplify.

y=5/5-4x/5

y=1- $\frac{4}{5}x$

The answer is $y=1-\frac{4}{5}x$

Need help with these two questions linear relations.

wel

Answer:

b. y = -7x + 4

1. y = -7(-5)+ 4 = 35+4= 39

2. -24= -7x + 4

-28 = -7x

4 = x

3. y = -7(0)+4= 4

4. 0 = -7x+4

-4= -7x

4/7 = x

c. 3y - 5x = 15

1. 3y - 5(6)

3y-30=15

3y=45

y = 15

2. 3(-10)-5x=15

-30-5x=15

-5x = 45

x = -9

3. 3y-5(0)=15

3y=15

y=5

4. 3(0)-5x=15

0-5x=15

-5x=15

x=-3
