Answer:

x = 3

Step-by-step explanation:

First you want to divide both sides by 5 to get 2x-4 = 2.

Afterwards, you add 4 to both sides of the equation. 2x = 6

Divide both sides by 2. x = 3

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

Kitty [74]

Answer:

$-14x-9y=6$

Step-by-step explanation:

We are given with two equations

first equation is $-7x-y=0$

second equation is

$7x+8y=-6$

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

$-7x-y=0$

$-7x-8y=+6$

Now add both equations, we get

$-14x-9y=6$
