What is c/22 + 668 = 684 I NEED HELP!!!!!!!!!!!!!!
scoundrel [369]

Answer:

352

Step-by-step explanation:

So first you need to subtract 668 from both sides.

c/22 + 668 = 684

          -668  -668

---------------------------

c/22 = 16

Then multiply both sides by 22.

c/22 * 22 = 16*22

c = 352

Check-

352/22=16

16+668=684
