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 -5c + 8c = 5c - 4z + 7 for c in terms of z.
| 1\(\frac{1}{5}\)z - \(\frac{7}{10}\) | |
| -11z - 1 | |
| -2\(\frac{1}{3}\)z + 2\(\frac{2}{3}\) | |
| -4z - 9 |
