Answer 2

Step-by-step explanation:

Hi there, here is Ur answer

3x+4y=25--------1 (LCM of 5 and 3 is 15)

5x-6y=-9---------2

Multiplying eq1 with 5

==> 15x+20y= 125

Multiplying eq2 with 3

==> 15x-18y= -27

15x +20y = 125

15x - 18y = -27

(-) (+) (+)

-------------------------------

0 - 38y = 152

-------------------------------

==> y = 152

----------- = 4 [ 38×1 = 38 ] [ 38×4 = 152 ]

38

Therefore y = 4

keeping y = 4 in equation 2

====> 5x- 6y = -9

====> 5x-6(4) = -9

====> 5x= -9+24

====> 5x= -15

====> x= -15

-------- = -3

5

Therefore, x= -3

y = 4

Hope it helps you friend
