-x = y + 3 incorrectx = -y + 3 correctWhat is the value of x?
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

1.Refer to the system of linear equations shown below. Which of the following statements gives the best choice for multiplying to solve this system using the elimination method?
3x−6y=4
6x+11y=−2
(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
(1 point)
13
−4
−13

5.Manny says he should multiply the first equation in the system of equations below by 3 and the second equation by 2, then add to eliminate x. Is there a more efficient way to solve this system? Explain your answer.
−2x+y=15
3x+4y=−12
(1 point)
No, there isn't a more efficient way to solve this system.
Yes, a more efficient way is to multiply the first equation by 4, add to eliminate y, then solve for x.
Yes, a more efficient way is to multiply the first equation by −4, add to eliminate y, then solve for x.
Yes, a more efficient way is to multiply the first equation by −4, add to eliminate x, then solve for y.

How would you wright this as a decimal number ?
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.
