Answer:

(x, y) = (8/3, -13/3)

Explanation:

The x-coefficients are opposites, so the x-terms can be eliminated simply by adding the equations.

(-4x -2y) +(4x +8y) = (-2) +(-24)

6y = -26

y = -26/6 = -13/3

Substituting into the first equation gives ...

-4x -2(-13/3) = -2

2x -13/3 = 1 . . . . . . . . divide by -2

2x = 16/3 . . . . . . . . . add 13/3

x = 8/3

The solution is (x, y) = (8/3, -13/3).

Answer 2

x = - 2 2/3

y = - 4 1/3

Explanation:

-4x -2y = - 2

4x +8y = -24

Now if you just add those 2 equations, what will happen is that the xs will cancel. They are equal but opposite in sign

6y = - 26 Now divide by 6

6y/6 = -26/6 Combine

y = - 4 2/6 = - 4 2/6

y = - 4 1/3

Now use the top equation to find x

-4x - 2(-4 1/3) = - 2

-4x + 8 2/3 = - 2 Subtract 8 2/3 from both sides

- 4x = - 2 - 8 2/3 Combine

- 4x = - 10 2/3 Divide by - 4

x = - 10 2/3 / - 4

x = - 2 2/3
