Answer:
No solutions exist because the situation describes two lines that have the same slope and different y-intercepts.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to call the numbers x and y.
A number is equal to twice a smaller number plus 3.
Greater number is x, and smaller is y. So
The same number is equal to twice the sum of the smaller number and 1.
This means that 
Equaling the values for x:
Since division by 0 does not exist, it means that there is no solution for the system.
4x + 5 - 5x
4 x 12+ 5
48 + 5 - 5
53 - 5
48
Answer:
Step-by-step explanation:
6 - 2x = 5x - 9x + 10 {add the like terms}
6 - 2x = - 4x + 10 {add (-6) to both side}
6 - 2x - 6 = - 4x + 10 - 6
-2x = - 4x + 4 {add 4x to both sides}
-2x + 4x = -4x + 4 + 4x
2x = 4 {divide both sides by 2}
2x/2x = 4/2
x = 2
There is 140% increase.
Step-by-step explanation:
Given,
10 gallons to 24 gallons
Old value = 10 gallons
New value = 24 gallons
Change = New value - Old value
Change = 24 - 10 = +14
The positive sign indicates the increase.
Percent increase = 
Percent increase = 
Percent increase = 140%
There is 140% increase.
