What's the solution to the equation, 2r−6=12

?

1 answer

To solve the equation 2r-6=12, we need to isolate the variable r.

First, we can start by adding 6 to both sides of the equation:

2r - 6 + 6 = 12 + 6

This simplifies to:

2r = 18

Next, we can divide both sides of the equation by 2 to solve for r:

2r/2 = 18/2

This simplifies to:

r = 9

Therefore, the solution to the equation 2r-6=12 is r = 9.
