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