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 4c + 2c = 3c + 5z + 9 for c in terms of z.
| \(\frac{8}{11}\)z + \(\frac{1}{11}\) | |
| 3z + 9 | |
| -\(\frac{2}{9}\)z - \(\frac{4}{9}\) | |
| -\(\frac{2}{3}\)z - 1\(\frac{1}{2}\) |
