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 7c - 6c = -c + 8z - 9 for c in terms of z.
| 1\(\frac{3}{4}\)z - 1\(\frac{1}{8}\) | |
| z + 1\(\frac{1}{5}\) | |
| -3z + 4 | |
| -\(\frac{1}{2}\)z - \(\frac{7}{12}\) |
