Question

The value of '$x$', which satisfies the equation $7x-3=0$, is:

• A. $\frac{3}{7}$
• B. $-\frac{3}{7}$
• C. $\frac{7}{3}$
• D. $-\frac{7}{3}$

Answer 1

The correct option is A $\frac{3}{7}$

Consider,
$7x-3=0....\left(1\right)$
$\Rightarrow 7x=3$
$\Rightarrow x=\frac{3}{7}$
Put the value to '$x$' in $\left(1\right)$ we get,
$7\left(\frac{3}{7}\right)-3=0$
Hence, $\frac{3}{7}$ satisfies the given equation.
