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 -8c - c = -2c - 2z + 4 for c in terms of z.
| \(\frac{11}{13}\)z - \(\frac{5}{13}\) | |
| 1\(\frac{2}{3}\)z + 1\(\frac{1}{3}\) | |
| 1\(\frac{2}{3}\)z - 1\(\frac{1}{3}\) | |
| \(\frac{1}{6}\)z - \(\frac{2}{3}\) |
