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 - c = 4c + 6z + 8 for c in terms of z.
| -1\(\frac{4}{9}\)z + \(\frac{4}{9}\) | |
| -\(\frac{4}{7}\)z + \(\frac{3}{14}\) | |
| -1\(\frac{1}{6}\)z - 1\(\frac{1}{3}\) | |
| 2\(\frac{3}{4}\)z + 1\(\frac{1}{4}\) |
