Answer:
All real numbers.
Step-by-step explanation:
Any value of r makes the equation true.
Interval Notation:
(- ∞, ∞)
Step 1: Simplify both sides of the equation.
5r + 3 = 5r + 3
Step 2: Subtract 5r from both sides.
5r + 3 - 5r = 5r + 3 - 5r
3 = 3
Step 3: Subtract 3 from both sides.
3 - 3 = 3 - 3
0 = 0
Therefor, your answer would be "All real numbers"
Hope this helps!
