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.
