Answer:

(-2, -4) or x = -2     y = -4

Step-by-step explanation:

Solve with subsitution

y-3x=2

y=-2x-8

1. Substitute -2x - 8 in for the y in y - 3x = 2                          (-2x - 8) - 3x = 2

2. Solve for x.  Combine like terms.                                               -5x - 8 = 2

3. Solve the one step equation.                                                          <u>  +8  +8</u>

                                                                                                              <u>-5x</u> = <u>10</u>

                                                                                                               -5     -5

                                                                                                                x = -2

4. Substitute the -2 in for x in either equation.                                y = -2x - 8

                                                                                                           y = -2(-2) - 8

                                                                                                           y = 4 - 8

                                                                                                           y = -4

Answer:

y-3x=2......1

y=-2x-8 ......2

substituting value of y in equation 1

-2x-8-3x=2

-5x=2+8

x=10/-5=-2

substituting value of x in equation 1

y-3×(-2)=2

y+6=2

y=2-6=-4

x=-2

y=-4
