====================================
If x + 2y = 6, what is the value of x ?
(1) 2x + y = 9
(2) 3x + 2y = 14
====================================
Statement 1
We get a system of equations.
x + 2y = 6 ==> x = 6 - 2y
2x + y = 9
2(6 - 2y) + y = 9
12 - 4y + y = 9
-3y = -3
y = 1
x = 4; Sufficient
Statement 1
We get a system of equations.
x + 2y = 6 ==> x = 6 - 2y
3x + 2y = 14
3(6 - 2y) + 2y = 14
18 - 6y + 2y = 14
-4y = -4
y = 1
and again x = 4; sufficient
