X= motor;  y= automobile;
if i wish to add a condition to the prob.;
if the number of motorcycle is 1/2 of the automobile;
then ;
x=[1/2]y............1.
2x+4Y=160';....2.

means 2 wheels (motor) +4(wheels0 auto=160 wheels;

2(y/2) +4y=160;

2y/2+4y=160;
5y=160;
y=32 automobiles;

x=32/2= 16 motor;

checking: 32 auto x 4wheels=128 wheels;
                16 motor x2wheels=32  wheels
                                            ---------
