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 - 6c = 3c + 5z + 6 for c in terms of z.
| \(\frac{5}{7}\)z + \(\frac{2}{7}\) | |
| -2\(\frac{4}{5}\)z - 1\(\frac{1}{5}\) | |
| -2\(\frac{3}{4}\)z + \(\frac{1}{2}\) | |
| -1\(\frac{2}{9}\)z - \(\frac{2}{3}\) |
