Answer:

x = 4

y = -4

(4, -4)

Step-by-step explanation:

-7x - y = -24

y = -3x + 8

-7x - (-3x + 8) = -24

-7x + 3x - 8 = -24

-4x = -16x

x = 4

To solve for y.

y = -3(4) + 8

y = -12 + 8

y = -4

Factor 35x + 28y im stuck on this and cannot get the answer

antoniya [11.8K]

Answer:

The answer is 7(5x+4y)

Step-by-step explanation:

Well you would have to first find what number is able to go in both numbers.

7 can go into 35 by 7·5

7 can also go into 28 by 7·4

So now we would simplify this by putting this in a distributive equation.
