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 7c - 2c = -6c + 7z - 3 for c in terms of z.
| \(\frac{9}{13}\)z - \(\frac{3}{13}\) | |
| z - \(\frac{1}{3}\) | |
| \(\frac{1}{2}\)z + 1 | |
| -\(\frac{4}{13}\)z - \(\frac{6}{13}\) |
