Hm, if Ariana wants to save money for her house, she should spend less money on fast food a month because if she spending $100 dollars for takeout coffee and spending at the same time a month for fast food. she should eat less fast food and less money for coffee because she would be spending way too much money because F = $200 and C = $100 dollars, so $200 + $100 dollars would be $300 dollars a month. she could still have takeout coffee however, not every month. The fast food needs to be taken out of her diet as well because its the fact its unhealthy and costing her way too much money, she should stop having fast food and not have coffee or the fast food EVERY MONTH, she could have the fast food evert 5 months and her takeout coffee every once a month. hopefully this helps ^^
You have to have one side equal x so I’ll solve one from each section
e) x = 2
5x = 12 - x add x to both sides 6x = 12 divide both sides by 6 x = 2
k) x = 3
15x + 4 = 10x + 19 move the 4 to the other side by subtracting on both sides 15x = 10x + 15 subtract 10x from both sides 5x = 15 divide by sides by 5 x = 3
