Question

4x + y =14
5x+6y=27
Cross multiplication

Answer 1

$4x + y = 14 \: \: \: \: i)$

$5x + 6y = 27 \: \: \: \: ii)$

multply 5 in i) equation and in ii) by 4.

$20x + 5y = 70$

$20x + 24y = 108$

by solving it

$5y - 24y = 70 - 108$

$- 19y = - 38$

$y = 2$

by putting the valu of y=2 in equation i)

$4x + y = 14$

$4x + 2 = 14$

$4x = 12$

$x = 3$

Therefore

$(x = 3 \: and \: y = 2)$
