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 3c + 7c = -5c - z + 2 for c in terms of z.
| -z + \(\frac{1}{4}\) | |
| 5\(\frac{1}{3}\)z - \(\frac{2}{3}\) | |
| \(\frac{1}{2}\)z - 1\(\frac{1}{8}\) | |
| \(\frac{1}{13}\)z + \(\frac{8}{13}\) |
