5x + 2y = -3 -----1equation
x + 5y = 4 ------2equation
__________________
5x + 2y = -3 multiply by 1
x +5y = 4 multiply by 5
__________________
5x + 2y = -3
5x + 25y = 20
- - - [subtracting both equations]
_______________________
- 23y =-23
_____________________
23y =23
y = 23/23
y =1
putting the value of y in 1 equation
5x + 2y = -3
5x + 2 = -3
5x = -3 -2
5x = -5
x =-5/5
x =-1
