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

Step-by-step explanation:

We are given with two equations

first equation is  

second equation is

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

Now add both equations, we get
