Question

Solve y = x2 + 2 for x.

Answer 1

Answer:

x = y - 2 / 2

Step-by-step explanation:

y = 2x + 2

2x + 2 = y

2x = y - 2

x = y - 2 / 2

Answer 2

Answer:

y/2 - 1 = x

Step-by-step explanation:

1. Subtract 2 from both sides. The equation will be y - 2 = 2x.

2. Divide both sides by 2. The equation will be (y - 2) / 2 = x.

3. Simplify the equation to y/2 - 1 = x.
