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 -2c - 7c = 7c + 6x - 7 for c in terms of x.
| 2\(\frac{1}{2}\)x - 1 | |
| -1\(\frac{1}{2}\)x + \(\frac{7}{10}\) | |
| -1\(\frac{4}{9}\)x + \(\frac{7}{9}\) | |
| -\(\frac{2}{5}\)x + \(\frac{1}{15}\) |
