y=x4−7; y=2
Y=2 (2)=x.4-7
2+4x-7
4x-7=2 get the variable alone by doing the same thing to both sides
4x=9
4x/4=9/4
y=9/4
x=9/4

Answer:
3.75
Step-by-step explanation:
Set up the following ratio:
2400 watt-hours 1 day
------------------------- = ----------
9000 watt-hours x days
Then do criss-cross-apple-sauce:
x*2400=9000*1
And then solve for x:
2400x=9000
x=9000/2400
x=3.75
Personally i think that if you use the pi symbol it would be more accurate because on a calculator there is an pi symbol √ which is the same it will give you an answer closer to an whole number.
