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 - 6c = 9c + 4x + 7 for c in terms of x.
| -\(\frac{10}{13}\)x - \(\frac{7}{13}\) | |
| 1\(\frac{2}{3}\)x - 2 | |
| -x - 2 | |
| -4x + 4 |
