Solving 2-Variable Linear Equation System
Systems of equations can be solved by using the method of elimination only.
Find the value of x and y
-4x - 2y = -12
4x + 8y = -24

Answer 1

Answer:

1) x = 6

y = 0

2) x = -4

y = 1

Step-by-step explanation:

1) -4x -2y = -12

putting x = 0

-4 × (0) -2 = -12

0 × -2y = -12

- y = -12/ 2

- y = - 6

y = 6

2) 4x + 8y = -24

putting y = 1

4x + 8 × (1) = -24

4x + 8 = - 24

4x = -24 -8

4x = -16

x = -16/4

x = -4
