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 -6c - 9c = -7c + 4z - 1 for c in terms of z.
| 4\(\frac{1}{3}\)z - 2\(\frac{2}{3}\) | |
| z + \(\frac{5}{8}\) | |
| 6z + 1 | |
| 13z - 1 |
