Question

Can i please have help thanks.

Answer 1

`q = 2(3r + 8)`

Explanation:

There are two variables, q and r in the expression given. To make r the independent variable, it simply means, make q the subject of the formula, so that variable q would be dependent on variable r. As r changes, q changes also.

Thus,

`q - 10 = 6(r + 1)`

Open the parenthesis

`q - 10 = 6r + 6`

Add 10 to both sides

`q - 10 + 10 = 6r + 6 + 10`

`q = 6r + 16`

`q = 2(3r + 8)`
