Answer:
(6y + 2)² = 4x²
Step-by-step explanation:
Given: x - 1 = 3y
Dividing by 3,
⇒ y =
Now, to determine 6y, multiply the equation throughout by 6y.
⇒ 6y =
⇒ 6y = 2(x - 1)
⇒ 6y = 2x - 2
Now, for 6y + 2, add 2 on both sides.
⇒ 6y + 2 = 2x - 2 + 2
⇒ 6y + 2 = 2x
Finally, Squaring both sides, will give us (6y + 2)².
⇒ (6y + 2)² = (2x)²
= 4x² which is the required answer.

Answer:
r/6 +2 = X
Step-by-step explanation:
We want to isolate X by itself to find its value. First transpose your -4 to the other side (note that -4 will become positive)
r + 2 +4 = 3x
r + 6 = 3x
To find the X, we get rid of the 3, so divide both sides by 3
r/3 + 6/3 = x
r/3 + 2 = x
OR
(r+6)/3 = x
Both works : )
