Question

Use elimination to solve the system.

x – y = −6

x + y = 8​

Answer 1

SOLUTION :-

$x - y = - 6 \: - eq(1) \\ \\ x + y = 8 \: - eq(2) \\ \\ adding \: eq(1) \: and \: eq(2) \: \\ \\ = > x + y = 8 \\ \\ \: \: \: \: \: \: \: x - y = - 6 \\ \\ \: \: \: \: \: - - - - - - \\ \\ = > 2x = 2 \\ \\ = > x = 1 \\ \\ from \: eq(2) \\ \\ y = 8 - x = 8 - 1 = 7$

Answer 2

Answer:

X = 1 , Y = 7

Step-by-step explanation:

X = Y - 6

Y - 6 + Y = 8

2Y = 14

Y = 7

and X = 1
