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 + 5c = -2c - z - 9 for c in terms of z.
| \(\frac{3}{8}\)z - \(\frac{7}{16}\) | |
| z - \(\frac{8}{11}\) | |
| -6z - 9 | |
| \(\frac{2}{13}\)z + \(\frac{8}{13}\) |
