Question

solve 2x+3y=4;3x-y+5=9​

Answer 1

Answer:

$2x + 3y = 4....eq1 \\ 3x - y = 4....eq2 \\ multiply \: with \: 3 \: in \: eq2 \: and \: \\ multiply \: ( - 1) \: in \: eq1 \\ then \: our \: equations \: are.. \\ - 2x - 3y = - 4 \\ 9x - 3y = 12 \\ then \: by \: solving \: these \: equations \: \\ by \: the \: elimination \: method.... \\ x = \frac{16}{11} </p><p>and \: y= \frac{4}{11} \\ hope \: it \: helps \: u...$
