Answer: I can answer both for you. 1. x=-69 2. -15/4=x
Step-by-step explanation: 1. 13+w/7=-8 First to get rid of the 7 we multiply both sides by 7.
13+w/7=-8
13+w=-56
Then we subtract both sides by 13 which gives us the answer
13+w=-56
x=-69
The final answer for the first is x=-69
For the 2nd we start of by adding 13 to both sides.
17=-13-8x
30=-8x
Then we divide both sides by -8
30=-8x
30/-8=-8x/-8
-15/4=x
The final answer for second is -15/4=x
Hope this helps!
