Question

In equation 2p-3=p+9, the value of P
● -12
● 12
● 6
● -6​

Answer 1

Answer:

p=12

Step-by-step explanation:

2p-3=p+9

2p-p=9+3

p=12

Answer 2

Solution:

Equation Given => 2p - 3 = p + 9

We have to check which values of p given in question will satisfy it.

(1) If p = -12

2p - 3 = p + 9

2(-12) - 3 = -12 + 9

-27 ≠ -3

LHS ≠ RHS

So, p = -12 doesn't satisfy the equation given.

(2) If p = 12

2p - 3 = p + 9

2(12) - 3 = 12 + 9

21 = 21

LHS =RHS

So, p = 12 satisfy the equation given.

(3) If p = 6

2p - 3 = p + 9

2(6) - 3 = 6 + 9

9 ≠ 15

LHS ≠ RHS

So, p = 6 doesn't satisfy the equation given.

(4) If p = -6

2p - 3 = p + 9

2(-6) - 3 = -6 + 9

-15 ≠ 3

LHS ≠ RHS

So, p = -6 doesn't satisfy the equation given.

The value of p = 12 satisfies the given equation.
