Solving an equation
We are given the following equation:
12c - 4 = 140 - 10
Solving for c means to isolate the variable and calculate the value to the right side of the equation.
We'll do it step by step.
First, we operate the numbers:
12c - 4 = 130
To isolate c, we must move the 4 from the left side to the right side.
Adding 4:
12c - 4 +4 = 130 + 4
Operating:
12c = 134
The last step is to divide by 12:
c = 134/12
Calculating:
c = 11.17
The result can be also given as a fraction.
Simplifying by 2:
c = 67 / 6.
