Question

5x+2y = 9,2x-3y = 4
resolver problema

Answer 1

$5x + 2y = 9 \\y = \frac{9 - 5x}{2} \\ 2 x - 3y = 4 \\ y = \frac{4 - 2x}{ - 3} \\ y = y \\ \frac{9 - 5x}{2} = \frac{4 - 2x}{ - 3} \\ - 27 + 15 x= 8 - 4x \\ \\ 19x = 35 \\ x = \frac{35}{19} \\ y = \frac{9 - 5( \frac{35}{19} )}{2} \\ y = \frac{ - 2}{19}$
