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