document.write( "Question 104811: I need help solving these equations- the last two I need to solve and graph. getting started on the 1st one I got as far as 21k-15 =12 I am thinking that the solution would be 3k. On the 2nd question- arrived at: 15-5x < 3x-9, where do I go from here? Last: Not sure how to solve the last one. Please help!\r
