Answer :
We will solve as follows:
[tex]-3<2x+7<13=-10<2x<6[/tex][tex]=-5We solve as if it were a simple function, in our case these are the steps to follow:*We subtract 7 from all expressions.
*We then divide by 2 all expressions.
*Now, we have solved for x, and therefore for each side of the inequality.
The main objective is to "leave" x alone, and the other sides of the inequation will be the answer.
