Question

thrice of which decreased by 1 gives 65.find the number​

Answer 1

Answer:

$11$

Step-by-step explanation:

Let the Number be $x$

Thrice of this number is

$3x$

Therefore, decreased by 1 gives 65

$3x - 1 = 65$

$3x = 66$

$x = 66\div 3 \\ x = 11$

Answer 2

Given: Thrice of a number decreased by $1$gives$65$.

We have to find the missing number.

• By using the concept of equation shifting, we are solving the above  equation.  
• For this, we will separate the variables on one side and the constant on  another side.
• Then, we will simplify the equation.  

We are solving in the following way:

We have,

Thrice of a number decreased by $1$gives$65$.

Let assume the number will be'$x$'.

From the above statement we can write:

$3x-1=65$

Solving the above equation further we get,

$=>3x=65+1\\=>3x=66\\\\=>x=\frac{66}{3} \\\\=>x=22$

Hence, the number will be$22$.
