Answer:
-3=x
Step-by-step explanation:
First you must add the X's on each side which gives you: 1x-2= -x - 4 - 4
Next you must add the first number 4 to the - 2 on the other side.
Then you do the exact same thing with the other number 4.
After that you get 1x+6=-x, then you subtract the 1 x with the -x to get 6= -2x.
Finally divide both sides by 2 and your final answer is -3 = x
Answer:
Step-by-step explanation:
ohn will need to sleep for 10.3 hours before his second exam so that the
he average of his two exam scores is an 80.

2
Cross multiply:
70+x = 160
x= 160-70
= 90.
If 8 hours of sleep = 70
x hours of sleep = 90
Cross multiply
8× 90 = 70 × x
720 = 70x
x = 720/70
x = 10.2857
≈ 10.3 hours of sleep
