Answer 1

$\huge\boxed{\texttt{\fcolorbox{red}{aqua}{Hey Mate}}}$

5x-8=7

substituting x=1 LHS is not equal to RHS so x=1 is not the solution of the given equation

similarly x=2 is not the solution of given equation

But substituting x=3 we get LHS = RHS

Hence x=3 is the solution of the given equation

Hope it helps you
