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 = -6c - 5x + 9 for c in terms of x.
| 1\(\frac{1}{8}\)x - \(\frac{7}{8}\) | |
| -4x - 9 | |
| \(\frac{2}{5}\)x + 1\(\frac{1}{5}\) | |
| 1\(\frac{4}{7}\)x + \(\frac{5}{7}\) |
