Question

Solve the systems using substitution.

6x + 2y = 0
4x + y = -1

Answer 1

Solve for y in the second equation then plug that into the first equation.

Answer 2

3x + 2y = -4
x + 2y = -8

5x - 4y = 14
x - 2y = -2

x + 3y = -4
4x + 5y = 5

x + 3y = -5
2x - y = 18

Would I do the same thing with these??
Solve for y and then plug it in?

Answer 3

Not all of them

Answer 4

I don't want answers but could you tell me how I would do them?

Answer 5

Solve for a single variable.

Answer 6

Gotcha and then just plug it in to find the other variable?

Answer 7

Yup, with practice it will be a breeze for you :)
