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