Question

Rearrange y =1/2x+1to make x the subject.

Answer 1

Answer:

The answer is x = 2y - 2

Step-by-step explanation:

Question: y = 1/2x + 1

Given:

equation: y = 1/2x + 1

Unknown:

Equation in x = ?

1. Move the x variable to the side that the y is on.

y = 1/2x + 1

-1/2x -1/2x

2. Move the y to the side of the y-intercept

y - 1/2x = 1

-y - y

3. Divide both sides by -1/2 or multiply by -2

-1/2x = -y + 1

*-2 -2(-y + 1)

The answer is x = 2y - 2

$y = \frac{1}{2} x + 1$

Multiply sides by 2

$2 \times y = 2 \times ( \frac{1}{2} x + 1)$

$2y =( 2 \times \frac{1}{2} x) + (2 \times 1)$

$2y = x + 2$

$x + 2 = 2y$

Subtract sides 2

$x + 2 - 2 = 2y - 2$

$x = 2y - 2$

Done...
