Question

Solve the equation. Then check your solution

v/7=3

A.-21
B.21
C.-4
D.10

Answer 1

Explanation:

`(v)/(7) = 3 \\`

`(v * 7)/(7) = 3 * 7 \\`

`v = 21 \\`

Answer 2

• Option B is correct i.e. 21

Explanation:

In the question we're provided with an equation that is :

• v/7 = 3

And we are asked to find the solution for the equation .

Solution : -

`\longrightarrow \: (v)/(7) = 3`

Multiplying by 7 on both sides :

`\longrightarrow \: \frac{v}{ \cancel{7} }* \cancel{7} = 3 * 7`

On further calculations , we get :

`\longrightarrow \: \blue{\boxed{v = 21}}`

• Therefore , solution for equation is 21 .That means option B is the correct answer.

Verifying :

We are verifying our answer by substituting value of v in the equation given in question :

`\longrightarrow \: (v)/(7) = 3`

Putting value of v :

`\longrightarrow \: \cancel{(21)/(7)} = 3`

By dividing 21 with 7 , we get :

`\longrightarrow \:3 = 3`

`\longrightarrow \: L.H.S=R.H.S`

`\longrightarrow \: Hence , \: Verified.`

• Therefore , our answer is valid .
