Tentukan nilai x dan y dari persamaan 2×+3y=15 x -2y=-3 Dengan cara: A. Eliminasi B. Substitusi​

Nilai y (Cara eliminasi)

2x + 3y = 15 | 1 | 2x + 3y = 15

x - 2y = -3 | 2 | 2x - 4y = -13

_______________________ -

7y = 28

y = 4

Nilai x (Cara subtitusi)

x - 2y = -3

x - 2(4) = -3

x - 8 = -3

x = -3 + 8

x = 5
