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 -8c - 9c = 2c - 3z - 1 for c in terms of z.
| -\(\frac{3}{5}\)z + \(\frac{1}{10}\) | |
| -\(\frac{3}{8}\)z - \(\frac{7}{8}\) | |
| -\(\frac{3}{5}\)z - 1 | |
| -1\(\frac{5}{12}\)z - \(\frac{7}{12}\) |
