- 8y + 9x = -5<br> 8y + 7x = -75
IRINA_888 [86]

Answer:

x = -5 , y = -5

Step-by-step explanation:

- 8y + 9x = -5

8y + 7x = -75

__________

0 + 16x = - 80

x = -80 / 16

x = -5

- 8y + 9x = -5

-8y + 9(-5) = -5

-8y - 45 = -5

-8y = -5 + 45

-8y = 40

y = 40/-8

y = -5

hope it helps!

Rewrite 8x - 7 as the product of two factors
kykrilka [37]

Answer:

factors are any group of number or expressions which, when multiplied, produce another number or expression.

Basic example:  4 can be broken into 2 factors---2 and 2.  2 times 2 = 4

Example using an unknown:

2X + 6 = 2 * (X + 3)

In the given problem, there is no whole-number common factor.  A normal convention would be to factor based on the unknown term----thus 8X is factored into 8 and X.

So:  8X + 7 = 8 ( X + 7/8 )

The following would also be correct:

8X + 7 = 4 ( 2X + 7/4 )

Step-by-step explanation:
