Solution

The correct option is C $0$
$\frac{2}{5} (5 x + 1) + \frac{3}{5} = 1$
$\frac{2}{5} (5 x + 1) = 1 - \frac{3}{5}$
$\frac{2}{5} (5 x + 1) = \frac{2}{5}$
$5 x + 1 = 1$
$5 x = 0$
$x = 0$

Q. Select the expression you will get for x and y if you solve the following equations using the cross multiplication method.

\sqrt{3} x = 2

\frac{x}{3} = 7 - \frac{y}{5}

\frac{2 + \frac{1}{3 \frac{4}{5}}}{2 + \frac{1}{3 + \frac{1}{1 + \frac{1}{4}}}} = x

then the value of x is

y = 5^{2 ({log}_{5} (x + 1) - {log}_{5} (3 x + 1))}

, then what is the value of

\frac{d y}{d x}

x = 0
