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 - 8c = 7c + 4z - 5 for c in terms of z.
| \(\frac{6}{17}\)z - \(\frac{9}{17}\) | |
| -2\(\frac{2}{5}\)z + 1 | |
| -3\(\frac{1}{5}\)z + \(\frac{4}{5}\) | |
| 1\(\frac{4}{5}\)z + 1\(\frac{3}{5}\) |
