(1 point)

Multiply the second equation by 12, so the x-variables are eliminated.

Multiply the first equation by 2, so the x-variables are eliminated.

Multiply the first equation by −11 and the second equation by 6, so the y-variables are eliminated.

Multiply the first equation by −2, so the x-variables are eliminated.
2.Given the following system, what should the second equation be multiplied by so that x is eliminated?

4x−y=9

x+3y=12

Hi there! :)

[tex]\large\boxed{-8.4}[/tex]

We can calculate the decimal by converting the fraction to an improper fraction, then dividing.

Derive the inpromper fraction by:

[tex]a\frac{b}{c} = \frac{c * a + b}{c}[/tex]

In this instance:

[tex]-8\frac{2}{5} = \frac{-8* 5 -2 }{5} = \frac{-42}{5}[/tex]

Divide:

-42 ÷ 5 = -8.4.

What is the value of x?

Answers

Answer:

x = 16

Step-by-step explanation:

(x+2) + (7x+2) + (3x) = 180

Add like terms  

7x + x + 3x = 11x

2 + 2 = 4

11x + 4 = 180

Subtract 4

11x + 4 = 180

11x = 176

Divide by 11

11x = 176

x = 16
