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 -4c + 7c = -5c + 4z - 3 for c in terms of z.
| -3z - 3 | |
| -3z + 1\(\frac{3}{5}\) | |
| -\(\frac{4}{7}\)z + \(\frac{9}{14}\) | |
| -z + \(\frac{1}{11}\) |
