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