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 -5c + 9c = 3c + 4x + 5 for c in terms of x.
| x + \(\frac{1}{5}\) | |
| \(\frac{5}{8}\)x - \(\frac{5}{8}\) | |
| 3x + 1 | |
| 7x + 4 |
