Question

Use elimination method to solve 4x – 2y = -4 and 4x + 8y = 16​

Answer 1

Answer:

x = 0, y = 2

Step-by-step explanation:

4x – 2y = -4 _____(1)

4x + 8y = 16 _____(2)

Subtracting eq. 1 and 2

-10y = -20

y = -20/-10

y = 2

Putting value of y in eq. 1

4x - 2y = -4

4x -2×2 = -4

4x -4 = -4

4x = -4+4

4x = 0

x = 0/4 = 0
