When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve 7c + 5c = c + 3x - 2 for c in terms of x.
| x + 2 | |
| -\(\frac{1}{3}\)x - \(\frac{1}{3}\) | |
| 2\(\frac{3}{5}\)x + 1\(\frac{3}{5}\) | |
| -\(\frac{3}{5}\)x - \(\frac{4}{5}\) |
