Answer 1

Answer:  The required number that Frank is thinking of is 7.

Step-by-step explanation:  Given that Frank is thinking of a number between 1 and 10 such that if he multiply the number by 8 and add 3, he get 59.

We are to find the number that Frank is thinking of.

Let x represents the number that Frank is thinking of.

Then, according to the given information, we have

$x\times 8+3=59\\\\\Rightarrow 8x+3=59\\\\\Rightarrow 8x=59-3\\\\\Rightarrow 8x=56\\\\\Rightarrow x=\dfrac{56}{8}\\\\\Rightarrow x=7.$

Thus, the required number that Frank is thinking of is 7.

Answer 2

The answer is 7  8x7=56 +3=59
