Given the equation:
7c - 8 - 2c = 17
Determine the value of c.
Solution:
In order to determine the value of c, we transpose first -8 to the other side of the equation, hence we must take note that in transposing a number, the sign changes.
7c - 8 - 2c = 17
5c = 17 + 8
5c = 25
Divide both sides by 5 in order to find the value of c.
c = 5
Final answer:
c = 5
