To find the answer to the first one you have to divide 7 by 6. The reason for this is s is being multiplied by 6. So division is the inverse. The answers is 1.16 repeating.
The other one is also simple. You have to isolate the w. Subtract 12 from w. Also subtract 12 from 6. Then since the w is negative multiple all by negative one to cancel it out. The answer would be 6
