Maria brought 17 packs of cola to a party, and each pack had 6 cans. Kira brought 9 cans of juice. How many cans did they bring in all?

Maria:

No. of cans in a pack = 6

No.of cans in 17 pack = 6 * 17 = 102 cans

No. of cans bought by Heather = 9 cans

Total cans = 102 + 9 = 111 cans

a = 3/28

Step-by-step explanation:

To start solving for a variable, you need to isolate it.

-4/3b = 4a

-4/3 divided by 4 equals -4/12 or -1/3

a = -1/3b

To completely solve for a we need to plug it back in and solve for b.

b = (4(-1/3b)) - 3/4

b = -4/3b - 3/4

7/3b = -3/4

b = -9/28

Finally, we can plug b back in to the previous equation we got for a to solve for a.

a = -1/3(-9/28)

a = 3/28

Furthermore, we can check if this is correct by plugging in 3/28 for a into the original problem and see if we get what we got for b (-9/28)
