The numbers.

Solution:

The first no. will be $\sf{3x(3×x=3x)}$

And,the second no. will be $\bf{15}$

A/Q

$\implies\sf{3x+15=42}$

$\implies\sf{3x=42-15}$

$\implies\sf{3x=27}$

$\implies\sf{x=}\dfrac{27}{3}$

$\implies\sf{x=9}$

Therefore,the first number will be ,

$\leadsto{3x=3×9=27}$

$\bf\underline\green{Verification:-}$

$\leadsto\bf{27+15=42}$

$\leadsto\bf{42=42}$
