4x−5=7+4y
subtract 7 from both side
4x - 5 -7 = 4y
4x -12 = 4y
divide by 4
4x/4 -12/4 = 4y/4
x-3=y
Answer:
y = x - 3
Step-by-step explanation:
Given equation,
4x - 5 = 7 + 4y
For finding the equation for y,
We need to isolate y in the left side of the equation,
Now,
Add 5 on the both sides of the above equation,
4x = 7 + 4y + 5
Subtract 4y on the both sides,
4x - 4y = 12
Subtract 4x on both sides,
-4y = 12 - 4x
Divide both sides by -4,
