Question

anonymous · Answer

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. 

15x - y = -6 
5x - 3y = -13

@Directrix @Nnesha

directrix · Answer

Take this and solve for y.

First Equation:  15x - y = -6 

y =15x +6

directrix · Answer

Into the second equation, substitute 15x + 6 for y.

Second Equation:

5x - 3y = -13

directrix · Answer

5x - 3y = -13

5x  - 3 * (15x + 6) = -13  --->

From there don out combine?

anonymous · Answer

Do you

directrix · Answer

Yes. I'm wondering if you have answer options for how the second equation is supposed to look after the substitution.

directrix · Answer

Or, is it you asking the question as you are solving the system?

directrix · Answer

If you want to solve for x, then you need to simplify this to solve for x.

5x - 3 * (15x + 6) = -13

anonymous · Answer

. 5(-15x - 6) - 3y = -13
 5(15x + 6) - 3y = -13
 5x - 3(15x + 6) = -13
 5x - 3(-15x - 6) = -13

Those are my answer choices

anonymous · Answer

Sooo c

directrix · Answer

I see an answer choice identical to this:

5x - 3 * (15x + 6) = -13 --->

directrix · Answer

C is what I think, too.
