Y=2x-7
therfor we can SUBSITUTE 2x-7 for y whereever we see y in the other equation
3x-2(2x-7)=9
3x-4x+14=9
-x+14=9
minus 14 both sides
-x=-5
mulitly -1
x=5
sub back
y=2x-7
y=2(5)-7
y=10-7
y=3
(5,3)

Answer:
The forklift truck can raise maximum of 43 boxes.
Step-by-step explanation:
We are given the following in the question:
Maximum limit of forklift truck =
1750 kilograms
Let x be the number of 40 kilogram boxes that this forklift truck can raise.
Thus, we can write the following inequality that describes the maximum number of boxes raised.
Thus, the forklift truck can raise maximum of 43 boxes.
I=(p)(r)(t)
I=(525)(.12)(1)
I=63
You have to add the $500 and the $25 first
The t will always be in years
