Question

Solve the equation 12p-11=25

Answer 1

SOLUTION :

TO SOLVE

The equation

$\sf{}12p - 11 = 25$

EVALUATION

The given equation is

$\sf{}12p - 11 = 25 \: \: \: \: ....(1)$

Adding both sides by 11 we get

$\sf{}12p - 11 + 11 = 25 + 11$

On simplification we get

$\sf{}12p = 36$

Dividing both sides by 12 we get

$\displaystyle \sf{} \frac{12p}{12} = \frac{36}{12}$

On simplification

$\sf{}p = 3$

So the required solution is

$\sf{}p = 3$

VERIFICATION

Putting p = 3 in both sides of (1) we get

$\sf{}(12 \times 3) - 11 = 25$

$\implies \sf{}36 - 11 = 25$

$\implies \sf{}25 = 25$

Hence Verified

FINAL ANSWER

The solution of the equation

12p - 11 = 25 is p = 3

Answer 2

Given:

12p-11 =25

To Find:

The value of p

Solution :

The given equation is 12p-11=25

=> 12p-11=25

When we transpose -11 to the right side it becomes +11

=> 12p = 25+11

=> 12p = 36

=> When we transpose, multiplication becomes division and division becomes multiplication.

=> p = 36/12

Now, Reduce the fraction.

=> 12 x 3 = 36, and 12 x 1 = 12

=> p = 3/1

=> p = 3.

Hence, the value of p is 3

Verify:

12p-11 =25

Substitute the value of p in the equation.

=> 12(3) - 11 = 25

=> 36 - 11 = 25

=> 25 = 25

Hence, Verified.
