Question

Zollie had a secret number. She found that the sum of 3 times her number add 70 equaled -50, what was her number?

Answer 1

Hint: The given question is of word problem, here we need to solve the given question by forming the mathematical equation for the given statement, in order to form the equation here we need to use the mathematical operation too.

Complete step by step answer:
Here in the given question we are provided with some of the condition with zollie, and we have to solve accordingly to get the secret number of the zullie, on solving we get:
Let the secret number of zollie be:
\[ \Rightarrow x\]
Now three times of her number:
\[ \Rightarrow 3x\]
Add 70 to his number:
\[ \Rightarrow 3x + 70\]
Now this equals to “-50”:
\[ \Rightarrow 3x + 70 = - 50\]
On solving for “x” we get:
\[
   \Rightarrow 3x + 70 = - 50 \\
   \Rightarrow 3x = - 50 - 70 \\
   \Rightarrow 3x = - 120 \\
   \Rightarrow x = \dfrac{{ - 120}}{3} = - 40 \\
 \]
Here we get the secret number of zollie.

Note: For solving such a question, here we need to first see the word statement and then accordingly will form the desired mathematical equation, and then can solve for the answer. Here the conversion of words to mathematical operations needs to be done correctly.
