Answer: 35 minutes
Step-by-step 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
[tex]7x=5x+10[/tex]
Subtract 5x from both the sides , we get
[tex]2x=10[/tex]
Divide both sides by 2, we get
[tex]x=5[/tex]
Now, the time spent by Jess = 7(5)=35 minutes
Hence, Jess was 35 minutes on computer.
