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 c + 5c = 9c - 9z + 6 for c in terms of z.
| -3\(\frac{1}{4}\)z + 2 | |
| -\(\frac{7}{9}\)z - 1 | |
| \(\frac{3}{11}\)z + \(\frac{8}{11}\) | |
| 1\(\frac{3}{4}\)z - \(\frac{3}{4}\) |
