Answer:
g(q) = [tex]\frac{5q}{8}[/tex]
Step-by-step explanation:
Given
- 7q + 12r = 3q - 4r
Rearrange making r the subject
Add 7q to both sides
12r = 10q - 4r ( add 4r to both sides )
16r = 10q ( divide both sides by 16 )
r = [tex]\frac{10q}{16}[/tex] = [tex]\frac{5q}{8}[/tex] , thus
g(q) = [tex]\frac{5q}{8}[/tex]
