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 5c - 9c = -2c - 8z - 8 for c in terms of z.
| 1\(\frac{3}{7}\)z + \(\frac{5}{7}\) | |
| \(\frac{1}{7}\)z - 1\(\frac{1}{7}\) | |
| \(\frac{6}{11}\)z + \(\frac{6}{11}\) | |
| -\(\frac{2}{13}\)z - \(\frac{3}{13}\) |
