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