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 + 7c = -5c - 6x + 9 for c in terms of x.
| 3\(\frac{1}{4}\)x - 1\(\frac{1}{2}\) | |
| \(\frac{2}{9}\)x - \(\frac{7}{9}\) | |
| 9x - 2 | |
| -13x + 9 |
