Hey friend !
3x + 2y + 25 = 0
2x - 3y - 70 = 0
Lets make the coefficients equal :-
3x + 2y + 25 = 0
6x + 4y + 50 = 0 -----> [1 ]
2x - 3y - 70 = 0
6x - 9y -210 = 0 -----> [ 2 ]
Subtracting equation 1 from 2 ,
6x - 9y -210 = 0
- 6x + 4y + 50 = 0
----------------------------------
-13 y = -260
y = 260 / 13
y = 20
we have got the value of y .
substitute this in the equation
2x - 3y=70
2x - 60 = 70
2x = 70 + 60
2x = 130
x = 130/2
x = 65
3x + 2y + 25 = 0
2x - 3y - 70 = 0

3x + 2y + 25 = 0
