Question

Solve each system by elimination 4x – 2y = 8
-6x + 2y = -2

Answer 1

x = -3, y = -10

or as an ordered pair (-3, -10).

Explanation:

4x – 2y = 8

-6x + 2y = -2 Adding these will eliminate y:

-2x + 0 = 6

x = -3 Now substitute for x in the first equation:

4(-3) - 2y = 8

-2y = 8 + 12

y = 20/-2 = -10.

Answer 2

Answer: x= -3; y = 5

Explanation:

4x – 2y = 8

-6x + 2y = -2

-2x = 6

x = 6

-2

x= -3

4x – 2y = 8

4 (-3) - 2y = 8

12-2y = 8

-2y = -12 + 8

y = -10

-2

y = 5
