-5x - 15 > 10 + 20x...subtract 10 from both sides, add 5x to both sides -10 - 15 > 20x + 5x ...simplify -25 > 25x...divide both sides by 25 -25/25 > x ....reduce -1 > x or x < -1 <===
I'm not sure what you are asking if your looking for the hours it should take him to get there it's about 10 hours adding the 2 and 3 he already drove... 5 left to go.. hope that helps
