Question

M=x1+x2/2 solve for x1

Answer 1

After solving for x1, we get

$x_1 = 2M-x_2$

Step-by-step explanation:

Given formula is:

$M = \frac{x_1+x_2}{2}$

In order to solve for x1, we have to isolate x1 on one side of the equation

So,

Multiplying the whole equation by 2:

$2M = \frac{x_1+x_2}{2} * 2\\2M = x_1+x_2$

Subtracting x2 from both sides

$2M-x_2 = x_1+x_2-x_2\\2M-x_2 = x_1$

so,

After solving for x1, we get

$x_1 = 2M-x_2$
