solve using elimination 6x+y=14 and x-4y=19.
6x + y = 14 --------- (1)
x - 4y = 19 ---------- (2)
multiply (2) by 6.
6x + y = 14 ----------- (3)
6x -24y = 114 ---------- (4)
subtract (3) from (4).
-25y = 100
divide both sides by -25.
y = -4
Substitute for y = -4 into (3).
6x - 4 = 14
6x = 18
x = 3
The solution is: x = 3, y = -4
