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 + c = -2c - 8z + 8 for c in terms of z.
| -1\(\frac{1}{3}\)z - \(\frac{1}{3}\) | |
| -3z + 2\(\frac{2}{3}\) | |
| -\(\frac{12}{17}\)z + \(\frac{8}{17}\) | |
| -8z - 7 |
