Answer:

The solution to the system of equations be:

$x=3,\:y=-1$

Hece, option B is correct.

Step-by-step explanation:

Given the system of equations

$\begin{bmatrix}x-3y=6\\ 2x+2y=4\end{bmatrix}$

Multiply x − 3y = 6 by 2: 2x-6y=12

$\begin{bmatrix}2x-6y=12\\ 2x+2y=4\end{bmatrix}$

$2x+2y=4$

$-$

$\underline{2x-6y=12}$

$8y=-8$

so the system of equations becomes

$\begin{bmatrix}2x-6y=12\\ 8y=-8\end{bmatrix}$

Solve 8y = -8 for y

$8y=-8$

Divide both sides by 8

$\frac{8y}{8}=\frac{-8}{8}$

$y=-1$

$\mathrm{For\:}2x-6y=12\mathrm{\:plug\:in\:}y=-1$

$2x-6\left(-1\right)=12$

$2x+6=12$

subtract 6 from both sides

$2x+6-6=12-6$

$2x=6$

Divide both sides by 2

$\frac{2x}{2}=\frac{6}{2}$

$x=3$

Therefore, the solution to the system of equations be:

$x=3,\:y=-1$

Hence, option B is correct.

pashok25 [27]

Answer:

First, take x off of both sides making it: “5 -4 = 3 + 10”

Then subtract 3, making it “3(-7) = 10”

Then do 3 multiply 3 by -7, getting -21 = 10

that is how you would find out the equation is false
