Answer:
Solving for x gives x=7
Step-by-step explanation:
First lets rewrite our equation clear, which from the question reads as :
Eqn(1).
This is a case of an equation with one variable <em>(i.e. one uknown)</em> denoted as .
The question is asking as to solve this equation and obtain the value of .
To do so we start by rewriting and simplifying the equation as follow:
which is the same as
Here we have a fraction on the left hand side reading as and an integer on the right hand side as . Thus we move the denominator of the fraction, in this case to the right hand side where we multiply it with , to eliminate our fraction and solve for as follow:
(Note how we transferd from the left hand side to the right hand side, the sign changed from <em>negative </em>to <em>positive). </em>
