How would u solve this liner system?

y = - 3x - 1

4x + 3y = 2

What is x and what is y?

We can solve it by substitution: y = - 3 x - 1.

So the 2nd equation becomes:

4 x + 3 * ( - 3 x - 1) = 2

4 x - 9 x - 3 = 2

- 5 x = 2 + 3

- 5 x = 5

x = 5 : ( - 5) = - 1

y = - 3 * ( - 1) - 1 = 3 - 1 = 2

Answer: x = - 1, y = 2.
