Question

Make x the subject in y=2x-pq

Answer 1

The value of x is equal to "$\dfrac{y + pq}{2}$".

Step-by-step explanation:

We have,

y = 2x - pq

To make x the subject in y = 2x - pq.

∴ y = 2x - pq

⇒ 2x = y + pq

⇒ x = $\dfrac{y + pq}{2}$

∴  x = $\dfrac{y + pq}{2}$

Thus, the value of x is equal to "$\dfrac{y + pq}{2}$".

Answer 2

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

Explanation:

Given equation is y = 2x – pq.

In this equation to make the subject as x.

y = 2x – pq

Add pq on both sides of the equation.

y + pq = 2x – pq + pq

y + pq = 2x

Divide by 2 on both sides of the equation.

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

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

Switch the sides of the equation.

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