Question

Jess spent 7x minutes on the computer. Her sister spent 5 x + 10 minutes on the computer, which was the same amount of time Jess spent. How many minutes was Jess on the computer?

Answer 1

7x = 5x + 10
-5x -5x
2x = 10
x = 5

7(5) = 35 minutes

Jess spent 35 minutes on the computer

Answer 2

Answer: 35 minutes

Explanation:

Given : Jess spent 7x minutes on the computer.

Her sister spent 5 x + 10 minutes on the computer, which was the same amount of time Jess spent.

Thus , we have

`7x=5x+10`

Subtract 5x from both the sides , we get

`2x=10`

Divide both sides by 2, we get

`x=5`

Now, the time spent by Jess = 7(5)=35 minutes

Hence, Jess was 35 minutes on computer.
