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