Question

11 = 1 + 3r + 2r

I really need help with this!!

Answer 1

Explanation:

11=1+5r

11-1=5r

5r=10

r=10/5

r=2

Answer 2

r = 2

Explanation:

I'm assuming we're finding r

11 = 1 + 3r + 2r

Add up the numbers with r

11 = 1 + 5r

Subtract both sides by 1

11 = 1 + 5r

-1 -1

10 = 5r

Divide both sides by the coefficient, 5, to isolate the variable, r

10/5 = 5r/5

r = 2
