X squared+y=18
x+y=6. use elimination method.(+y and +y cancels 
x squared -x=x
18-6=12
x=12
for y take one of the above equations
x+y=6(replace x with 12
12+y=6(collect the like terms
y=6-12
y=-6

so x=12 and y=-6

The gas tank of your car is 40% full. There are 8 gallons of gas in the tank. What is the capacity of the gas tank?
andreyandreev [35.5K]
Percentage by which the gas tank of the car is full = 40%
Amount of gas in the gas tank = 8 gallons
Let us assume the capacity of the gas tank = x gallons
Then
40% * x = 8
(40/100) * x = 8
4x/10 = 8
4x = 8 * 10
4x = 80
x = 80/4
   = 20 gallons
So the total capacity of the gas tank of the car is 20 gallons. I hope the procedure is clear to you.
