A system of equations is shown below 4x + 2y = 10
2x - 2y = 8
What is the value of x in the solution to the system?

[10 points, algebra 2]according to my answer key the restrictions are -1 and 4. but why not positive 1?

Solve the following inequalities and show the solution on a number line. 2x+3< 3(4x+5)

Tom is the deli manager at a grocery store. he needs to schedule employee to staff the deli department for no more that 260 person-hours per week. tom has one part-time employee who works 20 person-hours per week. each full-time employee works 40 person-hours per week. write and inequality to determine n, the number of full-time employees tom may schedule, so that his employees work on more than 260 person-hours per week. graph the solution set to this inequality.
