  • [tex]4x - 2y = 16 \\ \: \: x - 3y = 4 \\ \\(4x - 2y = 16) \times 3 \\ ( \: \: x - 3y = 4) \times 2 \\ \\ 12x - 6y = 48 \\ \frac{ \: \: 2x - 6y = 8}{10x = 40} - \\ \: \: \: \: \: \: \: \: \: x = \frac{40}{10} \\ \: \: \: \: \: \: \: \: \: x = 4 \\ \\ x - 3y = 4 \\ 4 - 3y = 4 \\ \: \: \: \: - 3y = 4 - 4 \\ \: \: \: \: - 3y = 0 \\ \: \: \: \: \: \: \: \: \: \: y = 0[/tex]
