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 -7c - 6c = 6c + 3z - 2 for c in terms of z.
| -\(\frac{1}{2}\)z + 1 | |
| -\(\frac{9}{13}\)z + \(\frac{2}{13}\) | |
| -\(\frac{1}{16}\)z - \(\frac{7}{16}\) | |
| \(\frac{1}{9}\)z + \(\frac{4}{9}\) |
