Question

Solve for r.

19 = 7 − –3r

Answer 1

r = 4

Explanation:

19 = 7 - -3r

19 = 7 + 3r

Then you do Inverse Operations So you have to Subtract

19 - 7 = 12

12 = 3r

Then you do Inverse Operation So you have to Divide

12/3 = 4

So

19 = 7 - -3(4)

So Let's Make Sure That It Is Correct

19 = 7 - -3(4)

19 = 7 - -12

19 = 7 + 12

So 4 Is The Correct Answer
