let bike be x and auto be y
so ,
x+y=17
2x+3y=46
now balance x+y =17 by multiplying the whole equation by 3
now we will get
3x+3y=51
now we shall solve the equations
3x+3y=51
2x+3y=46
now if we will subtract the equations then we will get
x=5
now we shall put the value of x
sp
x+y=17
5+y=17
y=17-5
y=12
so there are 5 bikes and 12 autos
or
we can take the values as x and 17-x then we shall put the value of tyres of bike and autos to get and equation like this 2x +3(17-x)=46 the we will get 2x+51 -3x=46 by solving we will get x as 5 and by putting the values the we will get the same value which is 5 bikes and 12 autos
