Respuesta :
Five less than 3 times a certain number is equal to the original number plus 7. The original number is 6.
How to estimate the original number?
From the above given information, we get
3x-5 = x+7
Adding 5 to both sides of the equation, we get
3x-5+5 = x+7+5
Simplifying the above equation
3x = x+12
Subtract x from both sides
3x-x = x+12-x
Simplify
2x = 12
Divide both sides by 2
[tex]$\frac{2 x}{2}=\frac{12}{2}[/tex]
Simplify
x = 6
Therefore, the original number is 6.
