Solve by elimination method : x - y = 2 , x + y = 12.

aalyn [17]

Answer: (7,5) X=7 and Y=5

Explanation:

Add the two equations together to eliminate y from the system.

x-y=2 + x+y=12
= 2x = 14

Divide both sides by 2

x=7

Substitute the value found for x into one of the original equations to solve for y

(7)-y=2

Move all terms to one side to make it easier

-y=2-7

Subtract

y=5
