Answer:
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
