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