Question

2x-3y=7 5x +2y=0 for x and y by elimination method​

Answer 1

Answer:

$2x - 3y = 7 - - - - (1) \\ 5x + 2y = 0 - - - - (2) \\ (1) \times 2 = > > 4x - 6y = 14 - - - (3) \\ (2) \times 3 = > > 15x + 6y = 0 - - - (4) \\from \: (3) \: and \: (4) = (3) + (4) \\ = > > 19x = 14 \\ x = \frac{14}{19} \\ 2( \frac{14}{19} ) - 3y = 7 \\ \frac{28}{19} - 7 = 3y \\ \frac{28 - 133}{19} = 3y \\ \frac{ - 105}{19} = 3y \\ \frac{ - 35}{9} = y$

Answer 2

....

2x-3y = 7........(i)

5x +2y = 0

now we will eliminate these eqh... first we will multiply first equation by 2 and second by 3..

4x-6y=14

15x+6y=0

on solving we get -

x=14/19

hops it helps u....☺☺
