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 -6c + 3c = 8c + z + 7 for c in terms of z.
| z + \(\frac{2}{3}\) | |
| \(\frac{1}{7}\)z - \(\frac{1}{2}\) | |
| \(\frac{7}{11}\)z + \(\frac{4}{11}\) | |
| -6z - 9 |
