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 10c + 4c = 9c + 4x - 9 for c in terms of x.
| -\(\frac{1}{3}\)x - \(\frac{7}{18}\) | |
| x - 9 | |
| \(\frac{1}{6}\)x - 1\(\frac{1}{3}\) | |
| 1\(\frac{3}{7}\)x - \(\frac{3}{7}\) |
