How to solve

6r+7=13+7r

Hello there! So for this equation, we are solving for the value of r. First off, let's subtract 6r from both sides. 6r - 6r cancels out. 7r - 6r is 1r or just simply r. That gets us 7 = 13 + r. Subtract 13 from both sides. The 13 on the right side cancels out. 7 - 13 is - 6. - 6 = r is left. There is nothing else to divide, so we have our value, but let's check it by plugging in - 6 as r.

6 * - 6 is - 36. - 36 + 7 is - 29. 7 * - 6 is - 42. - 42 + 13 is - 29. - 29 = - 29. There. r = - 6.

6r+7=13+7r

-6r. - 6r

7=13+1r

-13 - 13

-6/1=1/1r

-6=r
