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