Answer 2

Answer:

$3a - 42 = 18 \\ = > 3a = 18 + 42 \\ = > 3a = 60 \\ = > a = 60 \div 3 \\ = > a = 20$

So the value of a is 20.

Now let's verify it,

$3a - 42 = 18 \\ l.h.s \\ 3a - 42 \\ =( 3 \times 20) - 42 \\ = 60 - 42 \\ =</strong><strong>></strong><strong> 18 = r.h.s \\ so \: \: l.h.s = r.h.s$

Hope this helps you.
