Solve by the elimination method What is the solution 3x y
Solve by the elimination method. What is the solution?
3x – y = 0
x + 2y = 14
Solution
3x – y = 0 Eqn (1)
x + 2y = 14 Eqn (2)
Eqn (1) - Eqn (2)*3 =>
3x – y = 0
-3x - 6y = 42
-------------------------------
-7y = 42 => Y = -6
Substitute the value of Y = -6 in Eqn(2) => x - 12 = 14 => x = 26
