  • [tex]6x + 2y = 26 \\ x - 3y \: \: = 1 \\ \\ (6x + 2y = 26) \times 3 \\ (x - 3y \: \: = 1) \times 2 \\ \\ 18x + 6y = 78 \\ \frac{2x - 6y \: \: = 2}{20x = 80} + \\ \: \: \: \: \: \: \: \: \: x = \frac{80}{20} \\ \: \: \: \: \: \: \: \: \: x = 4 \\ \\ (6x + 2y = 26) \times 1 \\ (x - 3y \: \: = 1) \times 6 \\ \\ 6x + 2y \: \: \: = 26 \\ \frac{6x - 18y = 6}{20y = 20} - \\ \: \: \: \: \: \: \: \: \: y = \frac{20}{20} \\ \: \: \: \: \: \: \: \: \: y = 1[/tex]
