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