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 - 9c = 5c + 3x + 1 for c in terms of x.
| -1\(\frac{1}{4}\)x + 2\(\frac{1}{4}\) | |
| -x - \(\frac{1}{12}\) | |
| -1\(\frac{1}{3}\)x + \(\frac{1}{3}\) | |
| \(\frac{1}{3}\)x - 2 |
