What is the result of subtracting the second equation from the first? \begin{aligned} -7x-y &= 0 \\\\ 7x+8y &= -6 \end{aligned} −7x−y=0 7x+8y=-6 ​ =0 =−6 ​

Respuesta :

Answer:

[tex]-14x-9y=6[/tex]

Step-by-step explanation:

We are given with two equations

first equation is  [tex]-7x-y=0[/tex]

second equation is

[tex]7x+8y=-6[/tex]

we find the result of subtracting two equation

subtract the second equation from the first, so

first equation - second equation, multiply second equation by -1  and then add it with first equation

[tex]-7x-y=0[/tex]

[tex]-7x-8y=+6[/tex]

Now add both equations, we get

[tex]-14x-9y=6[/tex]
