Calculate the value of 𝑟r in the following linear equation: 𝑟−43=83r−4​ =8

Sure, let's solve the equation step by step:

1. The given equation is r - 4 = 8.
2. To isolate r, we need to get rid of -4 on the left side of the equation. We do this by adding 4 to both sides of the equation.
3. This gives us r - 4 + 4 = 8 + 4.
4. Simplifying this, we get r = 12.

So, the value of r in the given equation is 12.
