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