Explanation:


\tt{3x - 16 = 38}

We want to remove the 16 first. So , Since the original equation is - 16 , we are going to use the oppsite operation and add 16 to both sides.


\tt{3x - 16 + 16 = 38 + 16}

Simplify ! - 16 + 16 = 0 on the left. 38 + 16 = 54 on the right.


\tt{3x = 54}

Now , we need to think how to remove the coefficient 3. Since the opposite of multiplication is division , we are going to divide both sides by 3.


\tt{ (3x)/(3) = (54)/(3)}

Simplify ! 3 / 3 = 1 on the left and 54/3 = 18 on the right . So, our answer is 18.


\pink{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \underline{ \tt{x = 18}}}}}}}

Hope I helped ! ♡

Have a wonderful day / night ! ツ
