Answer:
-5
Step-by-step explanation:
We need to eliminate 22, so x is alone.
2x+22=12
So we subtract 22 from both sides.
2x+22=12
-22 -22
2x=-10
Now we have to divide 2 on both sides so x is alone.
2x=-10
÷2. ÷2
x=-5
We can always check
2(-5)+22=12
-10+22=12
12=12
1 minute = 60 seconds
300 seconds / 60 seconds = 5 minutes
