Question

For question number 1 pls help, and show work step by step

Answer 1

The answer for this problem would be
`\left[\begin{array}{ccc}r=7\end{array}\right] \\`.

We are going to solve your equation step-by-step.

Step 1: Subtract r from both sides.

7r−15−r=r+27−r

6r−15=27

Step 2: Add 15 to both sides.

6r−15+15=27+15

6r=42

Step 3: Divide both sides by 6.

6r/6=42/6

The answer for this is r=7.
