To solve the equation \( r5 - 6 = -1 \), we should follow these steps in order:
Step 1: Add 6 to both sides of the equation. \[ r5 - 6 + 6 = -1 + 6 \] This simplifies to: \[ r5 = 5 \]
Step 2: Divide both sides by 5. \[ \frac{r5}{5} = \frac{5}{5} \] This simplifies to: \[ r = 1 \]
However, based on your responses, let's see if we can find the right option:
After reviewing the original equation interpretation:
If you meant \( 5r - 6 = -1 \):
-
Add 6 to both sides: \[ 5r = 5 \]
-
Divide both sides by 5: \[ r = 1 \]
No options match \( r = 1 \) exactly, but if we sum correctly, the method still confirms basic algebra. Kindly double-check details for your question since input options provided vary contextually for r.
Continuing from your options, seems the best possible option is: None of the provided answers (i.e., \( r = 5, 25, 35, 10 \)) are suited from direct interpretation of standard variable steps, though they represented a processed intercept.
