Answer:
(2, - 6 )
Step-by-step explanation:
Given the 2 equations
x =
y + 5 → (1)
2x + 3y = - 14 → (2)
Substitute x =
y + 5 into (2)
2(
y + 5 ) + 3y = - 14 ← distribute and simplify left side
y + 10 + 3y = - 14
4y + 10 = - 14 ( subtract 10 from both sides )
4y = - 24 ( divide both sides by 4 )
y = - 6
Substitute y = - 6 into (1) for corresponding value of x
x = (0.5 × - 6 ) + 5 = - 3 + 5 = 2
Solution is (2, - 6 )
The system of equations that could be used to determine the number of small cars rented and the number of large cars rented is;
x + y = 10
x + y = 105x + 7y = 66
<h3>Simultaneous equation</h3>
- Small car = 5 people
- Large car = 7 people
- Total cars = 10
- Total number of people = 66
Let
Number of small cars rented = x
Number of large cars rented = y
x + y = 10
x + y = 105x + 7y = 66
