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 -3c + 8c = 7c + 9z + 5 for c in terms of z.
| -\(\frac{7}{10}\)z + \(\frac{1}{2}\) | |
| \(\frac{5}{9}\)z + \(\frac{4}{9}\) | |
| -\(\frac{6}{7}\)z - \(\frac{2}{7}\) | |
| -\(\frac{1}{10}\)z - \(\frac{1}{2}\) |
