Answer 2

Answer:

$x = \frac{1}{2} \\ \\ and \\ \\ y = \frac{1}{3}$

Step-by-step explanation:

$4x - 9y = - 1 \\ 6x + 15y = 8 \\ \\ 4x - 9y = - 1 \: ) \times 3\\ 6x + 15y = 8 \: ) \times 2 \\ - - - - - - - - - \\ 12x - 27y = - 3 \\ 12x + 30y = 16 \\ ( - ) \: \: \: \: ( - ) \: \: \: \: \: ( - ) \\ - - - - - - - - - \\ - 57y = - 19 \\ \\ y = \frac{ - 19}{ - 57} \\ \\ y = \frac{1}{3} \\ \\ then \: x = \\ \\ putting \: the \: value \: of \: y \: = \frac{1}{3} \: on \: \\ 4x - 9y = - 1 \\ \\ 4x - 9 \times \frac{1}{3} = - 1 \\ \\ 4x - 3 = - 1 \\ \\ 4x = 3 - 1 \\ \\ 4x = 2 \\ \\ x = \frac{2}{4} \\ \\ x = \frac{1}{2}$
