Answer: C=2
I know it seems difficult but it’s not as bad as it looks.
Explanation:
First you add 7 to both sides of the equation as shown:
3c-7+7=-c+1+7
Then you simplify giving you the equation 3c=-c+8
Then you add C to both sides of the equation: 3c+c=-c+8+c
Then you combine like terms giving you the equation of 4c=8
After that you divide both numbers by 4 giving you the fraction of 8/4 otherwise know as 2. Hope this helps, best of luck.
