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 2c + 9c = c - 4z - 5 for c in terms of z.
| \(\frac{7}{10}\)z + \(\frac{9}{10}\) | |
| -2\(\frac{1}{3}\)z + 2\(\frac{2}{3}\) | |
| -13z - 5 | |
| 1\(\frac{1}{11}\)z - \(\frac{7}{11}\) |
