Answer:
The solution to the system of equations is:
x = 2, and y = -1
Explanation:
Given the pair of equations:
4x + 5y = 3 ..........................................................................(1)
2x + 3y = 1............................................................................(2)
To solve this by elimination:
Multiply equation (2) by 2, to eliminate x
Equation (2) becomes
4x + 6y = 2 .........................................................................(3)
Subtract equation (1) from (3)
4x - 4x + 6y - 5y = 2 - 3
y = -1 ....................................................................................(4)
Multiply equation (1) by 3 and equation (2) by 5 to eliminate y
Equation (1) becomes
12x + 15y = 9 .......................................................................(5)
Equation (2) becomes
10x + 15y = 5 ........................................................................(6)
Subtract equation (6) from (5)
12x - 10x + 15y - 15y = 9 - 5
2x = 4
Divide both sides by 2
x = 4/2 = 2 ............................................................................(7)
From equations (7) and (4)
x = 2, and y = -1
The answer is y=(1/9)x + 60

Answer:
243/4(x^12)
Step-by-step explanation:
81x^12 x 3/4 = 243/4(x^12)
Answer:
x ≤ 204 crates
Step-by-step explanation:
Greatest weight of the container = 27500 kilograms
Weight of other shipment = 7100 kilograms
Weight of crates = 100 kilogram
x = number of 100 kilogram crates that can be loaded into the shipping container.
The inequality:
27500 ≤ 7100 + 100x
27500 - 7100 ≤ 100x
20,400 ≤ 100x
x ≤ 20,400 / 100
x ≤ 204 crates of 100 kilogram
