What is the answer to this equation? Algebra 1. |10-6r| - 3 = 13?

r = - 1 or r = 13/3

Step-by-step explanation:

Solve for r over the real numbers:

abs (10 - 6 r) = 16

Split the equation into two possible cases:

10 - 6 r = 16 or 10 - 6 r = - 16

Subtract 10 from both sides:

-6 r = 6 or 10 - 6 r = - 16

Divide both sides by - 6:

r = - 1 or 10 - 6 r = - 16

Subtract 10 from both sides:

r = - 1 or - 6 r = - 26

Divide both sides by - 6:

Answer: r = - 1 or r = 13/3
