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 - 2c = -8c - 2x - 3 for c in terms of x.
| \(\frac{1}{4}\)x - 1\(\frac{1}{2}\) | |
| x - \(\frac{1}{5}\) | |
| -8x - 5 | |
| -x + \(\frac{9}{10}\) |
