-4x-y=24 missing value

Lunna [17]

Answer:

For solving x x= -24+y/4 For solving Y y=−24−4x

Step-by-step explanation:

This is solving for x

Add y to both sides.

−4x=24+y

Divide both sides by -4

and the answer is

x= -24+y/4

THis is solving Y

Add 4x to both sides

−y=24+4x

Multiply both sides by -1

and the answer is

y=−24−4x
