Answer: x = [tex]\frac{p - r}{q}[/tex]
Step-by-step explanation:
From the question -qx + p =r
To solve for x, we make x subject of the formula.
First we need to subtract p from both-side of the equation
-qx + p -p = r -p
The equation becomes
-qx = r - p
We want to make the left hand side of the equation positive, so we simply multiply through by a negative sign (-)
The our equation becomes
qx = -r + p
We can rearrange the equation, hence;
qx = p - r
Divide both-side of the equation by q
[tex]\frac{qx}{q} = \frac{p - r}{q}[/tex]
(On the left hand side of the equation, the q numerator will cancel the q denominator, leaving us with only x)
x = [tex]\frac{p - r}{q}[/tex]
