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 -4c - 8c = -5c - z + 1 for c in terms of z.
| 1\(\frac{1}{3}\)z - 1 | |
| -2\(\frac{2}{3}\)z - 2 | |
| -z + \(\frac{7}{10}\) | |
| 7z + 1 |
