Johnny wants to ship a package to his friend a shipping company charges 2.49 for the first pound and 1.24 for each additional pound if it cost johnny 11.17 to ship the package how much did his package weigh

His package weighed 8 pounds. You find this by doing 11.17-2.49=8.64 for the first pound. Then you do 8.64/1.24=7 to find it was an additional 7 pounds. You add 7+1=8 to find his package weighed 8 pounds in total

2(10 - 13x) + 9x = -34x + 6020 - 26x + 9x = -34x + distributive property-17x = -34x + subtraction property (subtracted 20 from both sides)17x = addition property (added 34x to both sides)x = 40/ division property (divided both sides by 17)
