The one mistake is -27-10 they put -17 as the answer but it is actually -37. It is suppose to be: 8x-27-10-6x=15 Rephrase it: 8x-6x-27-10=15 Combine like terms: 2x-37=15 add 37 to each side of the equal sign (which cancels out the -37): 2x=52 then divide the two numbers by 2: 2x/2=52/2 which then gives you x=26... you can plug in 26 where you see x in the equation to check your work
