When she decided to combine the 5x and 2x she would have been subtracting the 2x leaving her with 3x-2=7which is 3x=9, x=3
7x+y-9=0
move constant to the left by adding its opposite to both sides. the sum of the two =0
Answer: sorry the answer is not clear.
Step-by-step explanation:
Your answer is 3:05.
You must add on to 9:40. So what I did was 9 + 5 = 14.
14 - 12 = 2.
So far it's 2:40.
25 minutes + 40. = 65.
Well there are 60 minutes in an hours. So 65 would be equal to 1H and 5min.
Now take that 1 hour. Add it to 2.
3 hours. And take your 5 minutes.
There! 3:05
