Solve for r (r + 2 \\ )/( \\ 2) = 3 r= ? ​

Question

Solve for r

`(r + 2 \\ )/( \\ 2) = 3`
r= ?
​

Answer 1

The solution to the equation is r = 4.

Step-by-step explanation:

To solve for r in the equation (r + 2) / 2 = 3, we need to perform a series of algebraic steps. The goal is to isolate r on one side of the equation. Here's the step-by-step process:

1. Multiply both sides by 2 to eliminate the fraction: 2 * ((r + 2) / 2) = 2 * 3
2. This simplifies to r + 2 = 6.
3. Subtract 2 from both sides to isolate r: r + 2 - 2 = 6 - 2
4. We are left with the solution r = 4.

Therefore, the solution to the equation is r = 4.
