5x+y+1=0, 2x-3y+8=0 Std 10

Answer»

5x + y +1 = 0

y = -1 - 5x -----1equation

______________,


Putting the VALUE of y in 2x- 3y +8=0

2x - 3( -1 -5x) +8

2x + 3 + 15X = -8

17x = -8 -3

17x = -11

x = -11/17

Putting the value of x in EQUATION 1

y = -1 - 5x

y = -1 - 5(-11/17)

y = -1 +55/17

y = (-17+55)/17

y = 38/17



I hope this will help you
