Using proportions is the easiest way to solve these type of questions. Proceed as such:
<u> 5 miles </u> = <u> 'x' miles </u>
1.5 hours 13.5 hours
'x' miles = (5 miles / 1.5 hours) * (13.5 hours)
'x' miles = 45 miles
First isolate the x. Always remember that the way you do this is the opposite of the what is happening to the number you want to move.
You want to move the -5 from the left side to the right side by doing the opposite and adding it to both sides.
Like: 27x-5=-5+11
27x-5+5=11+5
So 27x=11 Continue to isolate the variable

Answer
Find out the how many boxes of paper can the forklift move at one time .
To proof
Let us assume that the number of boxes be x.
As given
A forklift can carry up to 2500 pounds.
You want to move boxes of paper which each weigh 140 pounds.
The paper boxes are supported on one pallet which weighs 50 pounds.
Than the equation is become in the form
140x +50 ≥ 2500
140x ≥ 2500 - 50
140x ≥ 2450

x ≥ 17.5
Therefore the 18 boxes of paper can the forklift move at one time .
Hence proved
The solutions to the system of equations is 
Explanation:
Given the system of equations are
and 
We need to determine the solution to the system of equations.
Let us plot the equation
in the graph.
When
, we get, 
When
, we get, 
Thus, the coordinates are (0,6) and (3,0)
Let us plot the equation
in the graph.
When
, we get, 
When
, we get, 
Thus, the coordinates are (0,-7) and (5,0)
The solution to the system of equations is the point of intersection of the two lines.
Thus, the lines intersect at the point 
The approximate values of the point is 
Thus, the solution is
