If a, b.c are three differnt numbers, which of the following equation has only exactly one solution?
a. ax+b =ax=+b
b. ax =bx+c
c. ax+b = ax + c

B (:
ax+b=ax+b, plug in any number for a and b and it works

ax+b=ax+c, subtract ax from both sides and you get b=c... which isn't possible to solve if they are different numbers. therefore, it must be B

The answer is b because a and c have no solution
