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