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 - 4c = -2c + 2z + 1 for c in terms of z.
| -1\(\frac{5}{12}\)z + \(\frac{1}{2}\) | |
| -1\(\frac{1}{5}\)z - \(\frac{1}{5}\) | |
| \(\frac{3}{10}\)z + \(\frac{4}{5}\) | |
| 6z - 4\(\frac{1}{2}\) |
