Question

solve simultaneous equation 2x+3y =12 and x-y=1

Answer 1

Hey mate !!!


here is your answer!!!

given

x-y = 1

or

x = 1+ y -----------------(1) .


2x + 3y = 12 --------------------(2).


on putting the value of the equation 1 in equation 2 we get


=> 2 ( 1+y ) +3y = 12

=> 2+ 2y +3y = 12

=> 5y = 10

y = 2


now put the value of y in equation 1 we get

x = y+1

x = 2+1

x = 3


hence., x = 3

y = 1


hope it helps you dear!!!
