— 3x = у
— 9x — 5y = — 48

Sagot :

Step-by-step explanation:

plug in -3x for y

-9x-5(-3x)= -48

-9x+15x= -48. its +15 because negative times negative is.

positive

6x= -48 (-9 +15=6) now divide both sides by 6

x= -8

now you can solve for y by plugging in -8 for x

-3(-8) =y

24= y

x = -8 and y = 24

Explanation:

-3x = y ............................... (1)
-9x - 5y = -48 ................... (2)

From (1):
-3x = y
y = -3x

Sub (1) into (2):
-9x - 5(-3x) = -48

-9x + 15x = -48

6x = -48

x = -48/6

x = -8


Sub x = -8 into (1):
y = -3(-8)

y = + 24
