Answer 1

Answer: (-1, 4)

Step-by-step explanation: y=-2x+2, y=-4x Solve for the first variable in one of the equations, then substitute the result into the other equation.

Answer 2

Answer this question using SUBSTITUTION:

Substitution is a method to solving a system of equations through substituting one of the variables for another equation.

y + 2x = 2

y + 4x =0 (rewrite this equation so y is isolated: y =4x)

Since y=4x you can substitute the y in y +2x =2 and solve for x:

4x + 2x =2

6x = 2

x =
`(1)/(3)`

Now, plug in x into y =4x:

y = 4 (
`(1)/(3)`) =
`(4)/(3)` or
`1(1)/(3)`

x=
`(1)/(3)`

y =
`(4)/(3)` or
`1(1)/(3)`
