For this case we have the following equation:
We must find the solution.
We add similar terms from the right side of the equation:
We subtract 5 from both sides of the equation:
We subtract 7x on both sides of the equation:
Different signs are subtracted and the sign of the major is placed:
We multiply by -1 on both sides of the equation:![x = -3](/tpl/images/0350/5841/e8457.png)
Thus, the solution of the equation is
. -5 is not a solution to the equation.
