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