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 = -6c + 2z - 5 for c in terms of z.
| \(\frac{7}{9}\)z + \(\frac{4}{9}\) | |
| -2\(\frac{1}{6}\)z + 1 | |
| -1\(\frac{1}{2}\)z + 2\(\frac{1}{2}\) | |
| \(\frac{1}{11}\)z - \(\frac{7}{11}\) |
