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 -8c - 5c = 8c + 9z + 5 for c in terms of z.
| -\(\frac{7}{8}\)z - \(\frac{5}{16}\) | |
| 4z - 1 | |
| -1\(\frac{1}{2}\)z + 3 | |
| \(\frac{2}{3}\)z - \(\frac{1}{3}\) |
