2x + 3y = 26 dan 3x + 4y = 37 (substitusi) Tolong ya

cara substitusi

2x + 3y = 26
3x + 4y = 37.

• 2x + 3y = 26
2x = 26 - 3y
x = 18 - 3/2y

• 3x + 4y = 37
3(18 - 3/2y) + 4y = 37
54 - 9/2 y + 8/2 y = 37
54 - 1/2 y = 37
-1/2 y = 37 - 54
-1/2y = -17
y = 34

• 3x + 4y = 37
3x + 4(34) = 37
3x = 37 - 136
3x = -99
x = -33

maka, x = -33 dan y = 34

2x+3y= 26 》x3 ] 6x+9y =78
3x+4y= 37 》x2 ] 6x+8y = 74
kemudian dikurangi ya
y =4

Mencari nilai x
2x+3y = 26
2x+3(4)= 26
2x+12 = 26
2x = 26-12
2x = 14
x = 14/2
x = 7

Nilai x= 7 dan y= 4
