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 - 3c = 7c + 4z - 6 for c in terms of z.
| -7z + 6 | |
| z + \(\frac{7}{8}\) | |
| 3z + 9 | |
| z + \(\frac{9}{10}\) |
