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 + 3c = -8c - 2z + 6 for c in terms of z.
| \(\frac{2}{7}\)z - \(\frac{3}{7}\) | |
| \(\frac{9}{17}\)z + \(\frac{7}{17}\) | |
| -\(\frac{3}{11}\)z + \(\frac{4}{11}\) | |
| -\(\frac{5}{9}\)z + \(\frac{2}{3}\) |
