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 4c - 6c = 5c + 3x + 4 for c in terms of x.
| -9x - 4 | |
| 1\(\frac{3}{4}\)x + 2\(\frac{1}{4}\) | |
| -\(\frac{7}{15}\)x + \(\frac{1}{5}\) | |
| -\(\frac{1}{7}\)x - 1\(\frac{2}{7}\) |
