-x + 2y = 6

6y = x + 18


Let's rewrite these equations.


-x + 2y = 6

6y - x = 18


If we multiply the second equation by -1 we can add both of them.


-x + 2y = 6

-6y + x = -18


Add:


-x + (-6y) + 2y + x = 6 + (-18)

2y - 6y + x - x = 6 - 18

-4y = -12

y = -12/-4

y = 3


Substitute y in the equation:


-x + 2y = 6

-x + 2.3 = 6

-x + 6 = 6

-x = 6 - 6

-x = 0

x = 0


Option B.

Solve this system of equations using substitution. Put your answer in ordered pair form, (x,y).
Gelneren [198K]
2x + 5y = 2
-3x - y =-3

-3x - y = -3
y = 3x - 3

substitute y = 3x - 3 into the first equation.

2x + 5y = 2
2x + 5(3x - 3) = 2
2x + 15x - 15 = 2
17x - 15 = 2

solve for x in 17x - 15 = 2

17x - 15 = 2
17x = 2 + 15
17x = 17
x = 1

substitute x = 1 into y = 3x - 3

y = 3x - 3
y = 3(1) - 3
y = 3 - 3
y = 0

(1, 0) << the answer

hope this helped, God bless!

Answer:

Step-by-step explanation:

Let the no of cars be x and no of buses be y.

x + y = 60 -> y = 60 - x

6x + 30y = 600

with the available equations let us calculate the values of x and y.

6x + 30 * (60-x) = 600

6x + 1800 - 30x = 600

24x = 1200

x cars = 50

y buses = 10

maximum profit = 50 * 2.5 + 10 * 7.5 = $200
