Answer:
Step-by-step explanation:
Use the distributive property.
Take x outside the brackets.
(px - qx) = r
x (p - q) = r
divide by (p - q)
x (p - q)/(p - q) = r / (p - q)
x = r / (p - q)
Let's solve for x.
[tex]px-qx=r[/tex]
Step 1: Factor out variable x.
[tex]x(p-q)=r[/tex]
Step 2: Divide both sides by p-q.
[tex]\frac{x(p-q)}{p-q} =\frac{r}{p-q} \\\\x=\frac{r}{p-q}[/tex]
So, the answer to this problem is x=r/p-q
