Tentukan nilai x dan y pada 5x-3y-34=0 3x-5y-30=0

5x – 3y – 34 = 0………×3
3x – 5y – 30 = 0………×5, maka
15x – 9y – 102 = 0
15z – 25y = -150 = 0
—————————– –
0 + 16y + 48 = 0
16y + 48 = 0
16y = -48
y = -48/16
y = -3 ====> masukkan pers 2
3x – 5y – 30 = 0
3x – 5 . -3 – 30 = 0
3x + 15 – 30 = 0
3x – 15 = 0
3x = 15
x = 15/3
x = 5
nilai x = 5 dan nilai y = -3
