Question

One less than the product of a number and 3 is 5 more than the number itself

Answer 1

Answer:  The required number is 3.

Step-by-step explanation:  Given that one less than the product of a number and 3 is 5 more than the number itself.

We are to find the number.

Let x represents the given number.

Then, according to the given information, we have

$3x-1=x+5\\\\\Rightarrow 3x-x=5+1\\\\\Rightarrow 2x=6\\\\\Rightarrow x=\dfrac{6}{2}\\\\\Rightarrow x=3.$

Thus, the required number is 3.

Answer 2

Set it up as an equation.

3x-1=x+5

Now solve for x.

Add 1 to both sides and subtract x from both sides to isolate the x variable.

2x=6

Solve for x.

x=3
