# the number of solutions which a linear equation in one variable has, is ___ __ _ ___ _?

The number of solutions which a linear equation in one variable has, is  One , No or infinite solytions ?

It totally depend on the naturee of equation , As :

Case I  we have equation :  x  + 3  = 7   , Subtract both side by 3 and get

x = 4  ( One solution )

Case II : x + 2  =  x  , Subtract both side by x we get

2 = 0  but we know 2 $\ne$ 0 , So ( No solution )

Case III :  x  + 5 =  5  + x  , Subtract both side by 5 we get

x  = x  ( Infinite many solution )
