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 - 2c = -9c - 8z - 2 for c in terms of z.
| -1\(\frac{1}{5}\)z + 1\(\frac{3}{5}\) | |
| -6z - 2 | |
| 5z - \(\frac{1}{3}\) | |
| 1\(\frac{8}{9}\)z + \(\frac{2}{9}\) |
