Question

PLEASE HELP ASAP I WILL GIVE BRAINSLET TO THE CORRECT ANSWER!!!!!!!!!!

Answer 1

Therefore has one solution.

Step-by-step explanation:

Given equations:

6x + y = -7

-24x -7y = 25

Make y the subject:

6x + y = -7

y = -7 - 6x ..............equation 1

-24x -7y = 25

-7y = 25 + 24x

y = (25 + 24x)/-7 ..........equation 2

Solve them simultaneously:

(25 + 24x)/-7 = -7 - 6x

25 + 24x = -7 (-7 - 6x)

25 + 24x = 49 + 42x

42x - 24x = 25- 42

18x = -24

x =
`-(4)/(3)`

Then y is:

y = -7 - 6x

y = -7 - 6(
`-(4)/(3)`)

y = 1

Has one separate value of x and y: (
`-(4)/(3)` , 1 ); so it has one solution.
