Solve the system of equations - 4x + 2y = -30 and – 2x + 2y = -10 by<br> combining the equations.
I am Lyosha [343]

Answer:

  (x, y) = (10, 5)

Step-by-step explanation:

We notice that the y-coefficient is the same in both equations, and that the x-coefficient is smaller in the first equation. Subtracting one equation from the other will eliminate the y-variable. Subtracting the first equation from the second will result in a positive coefficient for x.

Subtracting the first equation from the second, we have ...

  (-2x +2y) -(-4x +2y) = (-10) -(-30)

  2x = 20 . . . .simplify

  x = 10 . . . . . divide by 2

Substituting for x in the second equation gives ...

  -2(10) +2y = -10

  2y = 10 . . . . add 20

  y = 5 . . . . . . divide by 2

The solution is (x, y) = (10, 5).
