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 = -4c - 3z + 4 for c in terms of z.
| 2\(\frac{2}{3}\)z + 3 | |
| -5z - 4 | |
| -\(\frac{3}{10}\)z - \(\frac{2}{5}\) | |
| -2z + 6 |
