State whether the following statement is True or False:
ab
If 2a = 2b = 45 then c =
a + b

Answer 1

$Given \: \pink { 2a = 2b = 45 }$

$Let \: 2a = 2b = 45 = c$

$i) 2a = 45 \implies a = \frac{45}{2} \: --(1)$

$ii) 2b = 45 \implies b = \frac{45}{2} \: --(2)$

$iii ) c = 45 \: --(3)$

$Now, \red{a + b}$

$= \frac{45}{2} + \frac{45}{2}$

$= 2 \times \frac{45}{2}$

$= 45$

$= \green {c}$

Therefore.,

$Given \: statement \:is \: \pink { TRUE }$
