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 2c - 7c = 4c - 7z + 1 for c in terms of z.
| \(\frac{1}{4}\)z + \(\frac{1}{2}\) | |
| z - \(\frac{1}{2}\) | |
| \(\frac{5}{14}\)z - \(\frac{4}{7}\) | |
| -1\(\frac{1}{2}\)z + 4 |
