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 -3c - 2c = c + 7z - 6 for c in terms of z.
| -\(\frac{4}{5}\)z + \(\frac{9}{10}\) | |
| -6z + 4\(\frac{1}{2}\) | |
| -2\(\frac{1}{4}\)z + 1\(\frac{1}{2}\) | |
| -\(\frac{11}{12}\)z - \(\frac{5}{12}\) |
