Rearrange the 2nd equation
-36a-24b-16c
divide the whole thing by 4 and you'll get
-9a-6b-4c
you'll realize it looks the same as your first equation except that all the + has become minus so the answer will be -7 instead for your new equation
-9a-6b-4c=-7
multiply the whole thing by 4 and you'll get
-36a-24b-16c = -28
so the answer you want is -28
Answer:
3x - 4 =9
Step-by-step explanation:
divide the entire equation by 3
9x/3 - 12/3 = 36/3
3x - 4 = 9
Answer:

i.e.

Nora's paper was farther than Max's plane flew by = 2 3/4 feet
i.e.

Thus the equation to show how far Max's paper airplane flew is:










Therefore, Max's paper airplane flew

Answer:
X + 50 = 130
Step-by-step explanation:
This is actually a subtraction equation although addition is how you set it up initially. X is the variable. You already have $50. You need $130.
To solve, subtract 50 from each side,
X + 50 - 50 = 130 - 50, and simplify,
X = 120.
Jordan will need $120 more to go to the Camp Rodeo Field Trip.
Hope this helps.
