True or True #8

$ac = bd$ and $c = d$ $\Rightarrow a = b$ , provided that $c$ and $d$ are not equal to 0.

Therefore, the true statement is " If $ac = bd$ and $c = d$ , then $a$ is NOT always equal to $b$ . For example, If $3 \times 0 = 2 \times 0$ and $0 = 0$ , then 3 = 2, which is wrong.

If $c=d=0$ , then $a$ and $b$ could be any number.

if c=d=0, they can not be cancelled. In that case, a may or may not be equal to b

condition is c=d but must not = 0

if c = d,unless provided that a = b then both products should always be equal, but if not then a should not be equal to the product of c and d, then a should not be equal to b. FALSE
