document.write( "Question 646132: I need to create a linear equation that shows how old I will be when I am 3 times my daughters age. Currently, I am 45 to her 11 and I was 34 when she was born. For some reason this math escapes me and if possible I would like each step explained so that I will be able to do the next one without help (high expectations on my part). I appreciate any help that you can offer.
