x - 2y = 2
----------- -
-y = -1
y = 1
x - 2y = 2
x - 2.1 = 2
x - 2 = 2
x = 2 + 2
x = 4
Nilai 2x - 5y = 2.4 - 5.1 = 8 - 5 = 3
Jawaban No.1 adalah C.3
2. 5x + 2y = 14900 x3 15x + 6y = 44700
4x + 3y = 13600 x2 8x + 6y = 27200
---------------------- -
7x = 17500
x = 2500
5x + 2y = 14900
5.2500 + 2y = 14900
5000 + 2y = 14900
2y = 14900 - 5000
2y = 9900
y = 9900/2
y = 4950
2x + y = 2.2500 + 4950 = 5000 + 4950 = 9950
