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 -5c + 9c = 9c - 4z + 3 for c in terms of z.
| \(\frac{13}{14}\)z - \(\frac{3}{14}\) | |
| 1\(\frac{3}{8}\)z - 1\(\frac{1}{8}\) | |
| \(\frac{1}{10}\)z - \(\frac{7}{10}\) | |
| -z - 1 |
