If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalen

t to y from the first equation is substituted into the second equation.
8x – y = –9
4x – 3y = –22

4x – 3(–8x – 9) = –22
4x – 3(8x + 9) = –22
4(8x + 9) – 3y = –22
4(–8x – 9) – 3y = –22

If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalent to y from the first equation is substituted into the second equation.

8x – y = –9
4x – 3y = –22

4x – 3(–8x – 9) = –22
4x – 3(8x + 9) = –22
4(8x + 9) – 3y = –22
4(–8x – 9) – 3y = –22

So here is the answer to the given question above.
If we are to use substitution method in order to solve the following system, the new equation would be <span>4x – 3(8x + 9) = –22, the answer is the second option.
Here is how I got the answer.
Let's take 8x - y = -22
So y = 8x + 22
Now, substitute the value of y to </span><span>4x – 3y = –22
and we get 4x - 3(8x +9) = -22.
Hope this answer helps. </span>
