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;

[email protected];

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

---------

160wheels.
