Solve the system of equations shown by substitution. y=x-5 5x+2y=4

x=2,y=-3

Step-by-step explanation:

y=x-5(1)

5x+2y=4...(2)

Let's substitute (1) into (2)

5x+2(x-5)=4

5x+2x-10=4

7x-10=4

Add 10 to both sides

7x=14

Divide both sides by 7

x=2

Substitute the value for x into (1)

y=x-5

y=2-5

y=-3

Therefore x is 2,y is-3

x = 2, y = -3

Step-by-step explanation:

y= x - 5

5x + 2y = 4

5x + 2(x - 5) = 4

5x + 2x - 10 = 4

7x = 14

x = 2

y = 2 - 5

y = -3

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
