You have to get the x to one side so you'll subtract 3x from -6x and 3x from 3x, the 3x will cancel out and -6x - 3x is -9x-7=11, you have to add 7 from both sides the 7+7 cancels out and also add 11+7 which leaves -9x=18, you have to divide -9x/-9 and do 18/-9, which gets you x=-2. Here's the work shown if you didn't what i said...
-6x-7=3x+11
-3x -3x
-9x-7=11
+7 +7
-9x=18
-9 -9
x=-2

Part B:
you didnt give any context. But to turn pounds into ounces multiply it the pounds by 16 (2lbs. × 16 = 32oz.)
and once you have the total number of ounces divide it by how many ounces her mom drinks in a day (ex. 32÷4= 9) and if that number is larger than 7 then yes, theres enough coffee
