Answer 1

Answer:

The number is 135.

Step-by-step explanation:

1) Form an equation

Three is subtracted from a number

⇒ $x-3$ (where x is "the number")

The difference is divided by 11

⇒ $\displaystyle \frac{x-3}{11}$

The result is 12

⇒ $\displaystyle \frac{x-3}{11}=12$

2) Solve the equation

$\displaystyle \frac{x-3}{11}=12$

Multiply both sides by 11

$\displaystyle \frac{x-3}{11}*11=12*11\\\\x-3=132$

Add 3 to both sides

$x-3+3=132+3\\x=135$

Therefore, the number is 135.

I hope this helps!
