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