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