Question

Thanks for the help

Answer 1

Explanation:

10q-5r=30

We want to solve for q

Add 5r to each side

10q -5r+5r= 30+5r

10q =30+5r

Divide each side by 10

10q/10=30/10 +5r/10

q = 3 +.5r

Answer 2

q = r/2 + 3

Explanation:

Add the opposite of the terms on the left that don't involve q. That means add 5r to both sides of the equation.

... 10q = 5r +30

Divide by the coefficient of q.

... q = (5/10)r + 3

... q = r/2 + 3 . . . . . . simplify
