A cleaning company charges x dollars per hour to clean floors and y dollars per hour to clean the rest of the house
Nina [5.8K]

Answer:

(15,18)

Step-by-step explanation:

write two equations with the information provided.

2x + 3y = 84

x + 4y = 87

use the property of substitution to answer.

x + 4y = 87,   x = 87 - 4y

2(87 - 4y) + 3y = 84

174 - 8y + 3y = 84

174 - 84 = 8y - 3y

90 = 5y

90/5 = y

y = 18

Add the value of Y to an original equation. Solve for X

2x + 3(18) = 84

2x + 54 = 84

2x = 84 - 54

2x = 30

x = 30/2

x = 15

Y + 2x = 4 How do I complete this?
Leviafan [203]
To solve this, what you will need to do is find the solution of one variable and then substitute it and solve for the other.

Here’s how to solve:
y+2x=4
-2x -2x

y=4-2x

4-2x + 2x =4

4=4

So if you’re trying to see if it is true, then your answer is that it’s true.

If you’re trying to find the linear equation, then your answer is y=-2x+4.
