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 + c = 8c - 6z - 6 for c in terms of z.
| -\(\frac{9}{14}\)z + \(\frac{1}{14}\) | |
| 7z + 6 | |
| -4z - 3 | |
| -2\(\frac{1}{2}\)z - 2 |
