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