Answer 1

$</p><p>6x - 3y = 15| \div ( - 3) \\ 2x + 3y = 1 \\ \\ - 2x + y = - 5 \\ 2x + 3y = 1 \\ \\ \\4y = - 4 \\ y = 1 \\ \\ \\ 2x + 3( - 1) = 1 \\ x = 2$

$10x - 8y = 15 \\ 10x + 4y = 27 | ( - 1) \\ \\ - 10x - 8y = 15 \\ - 10x - 4y = - 27 \\ \\ - 12y = - 12 \\ y = 1 \\ \\ 10x - 8 \times 1 = 15 \\ x = \frac{23}{10}$
