Question

18-3p=6p+9 then p is​

Answer 1

Given :–

• An equation, 18 – 3p = 6p + 9.

To Find :–

• Value of p.

Solution :–

Given equation is,

⟹ 18 – 3p = 6p + 9

We have to find the value of p.

So,

⟹ –3p – 6p = 9 – 18

⟹ –9p = –9

⟹ p = $\dfrac{\cancel- \cancel{9}}{\cancel- \cancel{9}}$

⟹ p = 1

Hence,

The value of p is 1.

Check :–

Value of p is,

• p = 1

Now, put the value of p in the given equation and solve the L.H.S. and the R.H.S.

Equation is, 18 –3p = 6p + 9

⟹ 18 – 3(1) = 6(1) + 9

⟹ 18 – 3 = 6 + 9

⟹ 15 = 15

Since, the L.H.S. and the R.H.S. are equal.

So, the value of p is 1 is correct.

Answer 2

Answer:

=> p = 1

Step-by-step explanation:

Given that:-

$18-3p=6p+9$

To find:- The value of the expression:

Here we will use the transposition method.

As we have,

=> $18-3p=6p+9$

Now, rearrange the terms we get

=> $-3p+18=6p+9$

Subtract $18$ from both sides, we get

=> $-3p+18-18=6p+9-18$

=> $-3p=6p-9$

Subtract both sides by $6p$, we get

=> $-3p-6p=6p-9-6p$

=> $-9p=-9$

Divide both sides by $-9$, we get

=> $p = 1$

Hence, the required solution is 1.
