Solve the following system of equations , and find the ordered pair. X =-y-6 and -7x +6y=-10
Blababa [14]

Given:

There are given the equation:

\begin{gathered} x=-y-6...(1) \\ -7x+6y=-10...(2) \end{gathered}

Explanation:

From the equation (1):

Put the value of x into the equation (2):

So,

From the equation (2):

\begin{gathered} \begin{equation*} -7x+6y=-10 \end{equation*} \\ -7(-y-6)+6y=-10 \\ 7y+42+6y=-10 \\ 13y=-10-42 \\ 13y=-52 \\ y=-4 \end{gathered}

Now,

Put the value of y into the equation (1):

So,

From the first equation:

\begin{gathered} \begin{equation*} x=-y-6 \end{equation*} \\ x=-(-4)-6 \\ x=4-6 \\ x=-2 \end{gathered}

Final answer:

Hence, the ordered pair of the solution is shown below:

(-2,-4)

Help Plss simply can u show step by step ?-4(8x-4)+3x
Vikentia [17]

Answer:

-4(8x-4)+3x = -29x+16

Step-by-step explanation:

1. Simplify -4(8x-4) by using the distribution property:

<u>-4(8x) = -32x and -4(-4) = 16 so -4(8x-4) = -32x+16</u>

2. Add 3x to the remaining equation:

<u>-32x+16+3x = -29x+16 </u>

3. The answer is:

<u> -29x+16 </u>
