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 - c = -4c - 5z + 9 for c in terms of z.
| 1\(\frac{5}{6}\)z + 1\(\frac{1}{3}\) | |
| 1\(\frac{1}{3}\)z - 3 | |
| -\(\frac{1}{2}\)z + 1\(\frac{1}{3}\) | |
| -\(\frac{1}{6}\)z - \(\frac{1}{3}\) |
