c/7+2=1

c/7=-1
c=-7

c/7+2=1

c/7=1-2=-1
c=-7

To solve the equation c/7 + 2 = 1, we need to isolate the variable c.

Here are the steps to solve it:

1. Start by subtracting 2 from both sides of the equation: c/7 = 1 - 2
Simplifying the right side gives us: c/7 = -1

2. To eliminate the fraction, multiply both sides of the equation by 7. This will cancel out the denominator on the left side: 7 * (c/7) = 7 * (-1)
Simplifying gives us: c = -7

Therefore, the solution to the equation c/7 + 2 = 1 is c = -7.
