Question

2r +8= 26
» What is the value of r?
meters

Answer 1

• 
  `\boxed{\sf{r=9}}`

Explanation:

To find the value of r, isolate it on one side of the equation.

`\sf{2r+8=26}`

First, you have to subtract by 8 from both sides.

`\sf{2r+8-8=26-8}`

Solve.

Subtract the numbers from left to right.

26-8=18

2r=18

Divide by 2 from both sides.

`\sf{(2r)/(2)=(18)/(2) }`

Solve.

Divide the numbers from left to right.

18/2=9

r=9

• Therefore, the correct answer is r=9 meters.

I hope this helps. Let me know if you have any questions.

Answer 2

r = 9 meters

Explanation:

2r + 8 = 26 <== subtract 8 from both sides

- 8 - 8

2r = 18 <== divide both sides by 2 to isolate the variable

/2 /2

r = 9 meters

Hope this helps!
