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 2c + c = -8c + 9z + 2 for c in terms of z.
| z + 1\(\frac{2}{7}\) | |
| \(\frac{4}{5}\)z + \(\frac{1}{5}\) | |
| 3\(\frac{1}{3}\)z - 3 | |
| -\(\frac{1}{2}\)z + \(\frac{3}{5}\) |
