4x - y = 18
Add both the equations together.
3x + 4x + y - y = 17 + 18
7x = 35
x = 5
Plug in x = 5 into any equation, and solve for y.
3(5) + y = 17
15 + y = 17
y = 2
Your solution is (5,2).

Answer:
In 0.3 gallon of fuel, the car will travel 20 km.
A is the correct option.
Step-by-step explanation:
We have been given that in 1 gallon of fuel the car can travel 40 miles.
Now, 1 mile = 1.6 km.
Hence, in 1 gallon the car travel 40×1.6 = 64 km
Let the car will consume x gallons of fuel to travel 20 km.
Thus, we have the equation
ON solving for x
Therefore, in 0.3 gallon of fuel, the car will travel 20 km.
A is the correct option.
Answer: The car would need 0.3 gallons of fuel to travel 20km.
Step-by-step explanation: 40mile x 1.6km = 64km
1 gallon 1 mile 1 gallon
20km ÷ 64km = 0.3125

so therefor (4x-2) must be less than 6 and less than 4
it must be
6>4-2x and 4<4-2x
find the intersection
6>4-2x
add 2x to both sides
6+2x>4
subtract 6
2x>-2
divide by 2
x>-1
4>4-2x
add 2x
4+2x>4
subtract 4
2x>0
x>0
so we have
x>0
and x>-1
the range of x>-1 includes most of x>0 so the answer is
x>-1

OK. Thanks for clarifying that.
-- If the original number is negative, then its opposite is greater.
-- If the original number is positive, then its opposite is smaller.
-- So the opposite of a number is sometimes greater than the number itself.
example -3 the opposite is 3
it can be smaller
example 3 the opposite is -3
