Question

solve the following equation 9/7-6x =15​

Answer 1

Given:

The eqaution:

$\sf{\dfrac{9}{7} - 6x = 15}$

What To FInd:

We have to find and solve the equation and find the value of x.

Solution:

⇒ $\sf{\dfrac{9}{7} - 6x = 15}$

Take 1 as the denominator in 6x,

⇒ $\sf{\dfrac{9}{7} - \dfrac{6x}{1} = 15}$

Take the LCM of 7 and 1 ie 7,

⇒ $\sf{\dfrac{9}{7} - \dfrac{6x \times 7}{1 \times 7} = 15}$

Multiply,

⇒ $\sf{\dfrac{9 - 42x}{7} = 15}$

Take 7 to RHS,

⇒ $\sf{9 - 42x = 15(7)}$

Mutiply 15 by 7,

⇒ 9 - 42x = 105

Take 9 to RHS,

⇒ -42x = 105 - 9

Subtract 9 to 105,

⇒ -42x = 96

Take -42 to RHS,

⇒ $\sf{x = -\dfrac{96}{42}}$

Simplify the rational number,

⇒ $\sf{x = - \dfrac{16}{7}}$

∴ Hence the value of x is $- \dfrac{16}{7}$.
