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