Question

Solve for the value of r.

Answer 1

Answer:

r=14

Step-by-step explanation:

7r+6=8r-8

14=r

r=14

Answer 2

Answer:

r = 14

Step-by-step explanation:

Since both angles are equivalent to each other solve for r:

7r + 6 = 8r - 8 (subtract 6 from -8)

7r = 8r - 14 (subtract 8r from 7r)

-r = -14 (divide each side by -1)

r = 14

Then plug the value of r (14) back into both parentheses:

7 * 14 + 6 = 104°

8 * 14 - 8 = 104°

The final answer is r = 14, and both angles equal to 104°
