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 -c - 3c = 4c + 7z + 8 for c in terms of z.
| \(\frac{1}{2}\)z - \(\frac{3}{4}\) | |
| 6z - 6 | |
| 2z + 1 | |
| -2z - 1\(\frac{3}{5}\) |
