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 - c = c + 8z + 7 for c in terms of z.
| \(\frac{6}{11}\)z - \(\frac{2}{11}\) | |
| -\(\frac{1}{3}\)z - 1 | |
| -1\(\frac{1}{7}\)z + \(\frac{6}{7}\) | |
| -3z - 2\(\frac{1}{3}\) |
