The teacher will be very surprised to see your correct solution π
The solution
Detail solution
Given the equation
$$\frac{\log{\left(1 \right)}}{7} \left(7 x - 3\right) = \frac{\log{\left(5 x + 11 \right)}}{\log{\left(1 \right)}}$$
Transfer the right side of the equation left part with negative sign
$$\tilde{\infty} \log{\left(5 x + 11 \right)} = 0$$
Let's divide both parts of the equation by the multiplier of log =Β±oo
$$\log{\left(5 x + 11 \right)} = 0$$
This equation is of the form:
log(v)=p
By definition log
v=e^p
then
$$5 x + 11 = e^{\frac{0}{\tilde{\infty}}}$$
simplify
$$5 x + 11 = 1$$
$$5 x = -10$$
$$x = -2$$
