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