What is the solution to the system 3x+2y=-3 and 9x +4y=3

x=3, y=-6

Step-by-step explanation:

As you know there are many ways to solve this question! First is Subsitutuion, Second is Elimination, and Third is Graphing!

Let’s begin with our detailed

As you know subsitution is solving for a variable and then it can be used as a variable substitution to figure out x and y.

So in our system of equations:

I will just take one equation and solve for x but it actually dosent matter which variable you subsitutue and solve for.

To eliminate this question we can divide the top part by -3:

Let‘s sum these system of equation and we get:

We can now insert y as -6 and solve for x:

So,

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,
