Answer 2

The given question is 3x+2y-5=0 and x-3y-9=0.

we have to solve these 2 equations by substitution method.

3x+2y=5-------1

x-3y=9-----------2

equation 2 can be written as

x=9+3y---------3

sub equation 3 in equation 1

$3(9 + 3y) + 2y = 5 \\ 27 + 9y + 2y = 5 \\ 27 + 11y = 5 \\ 11y = 5 - 27 \\ 11y = - 22 \\ y = \frac{ - 22}{11} \\ y = - 2$

substitute y in equation 3 to get x

$x = 9+ 3y \\ x = 9 + 3( - 2) \\ x = 9 - 6 \\ x = 3$

Therefore the values of x and y is 3 and -2
