Answer:

Step-by-step explanation:

We have two simultaneous equations.

(1) y = 2x + 50

(2) y = 4.5x

1. Subtract (1) from (2)

0 = 2.5x - 50

2. Add 50 to each side

2.5x = 50

3. Divide each side by 2.5

x = 20

Pilar must sell 20 items to break even.

Solve the system using substitution. Show all work.<br> ( 4х + 5y = 7<br> у = 3х + 9

Lina20 [59]

Answer:

(4x+5y=7

y=3x+9

4x+5(3x+9)=7

4x+15x+45=7

19x=7-45

19x= -38

19×/19=-38/19

x= -2

whlie y=3x+9

y=3(-2)+9

y= -6+9

y=3 end solution

x= -2,y= 3

The equation 7x + 3x - 18 = 6(x+3) is 9

<h3>What is equation?</h3>

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

given:

7x + 3x - 18 = 6(x+3)

7x + 3x - 18 = 6x+18 [Distributive Property]

10x-18= 6x+18 [Addition Property of Equality]

10x-6x= 18+18 [Combine Like Terms ]

4x=36 [Subtraction Property of Equality]

4*x=36 [Multiplication Property of Equality]

x=36/4 [Division Property of Equality]

x=9
