Tentukan penyelesaian menggunakan metode substitusi 3x+5y=26 4x-2y=11

System of Linear Equation in Two Variable.

We will solving this problem by substitute x variable.
3x + 5y = 26 → x = (26 - 5y) / 3
4x - 2y = 11
4/3 (26 - 5y) - 2y = 11
104/3 - 26/3 y = 11
104 - 26y = 33
y = 71 / 26

x = [26 - 5(71/26)] / 3
   = 107 / 26
