What is the value of x in the solution to the following system of equations? x − y = −3 x + 3y = 5 answer for blank 1:

So for this, we will be using elimination method. With these two equations, subtract (x - y = -3) from (x + 3y = 5) to get . From here we can solve for y.

For this, just divide both sides by 4, and your answer will be

Now that we have the value of y, substitute it in into either equation to solve for x:

In short, x = -1.

answer: y = -12x + 108

step-by-step explanation: do (y = m x+b) formula.
