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