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 -4c + c = 9c + 4z + 2 for c in terms of z.
| 7z + 2 | |
| -\(\frac{3}{13}\)z - \(\frac{2}{13}\) | |
| \(\frac{2}{3}\)z + \(\frac{2}{3}\) | |
| z - 1\(\frac{1}{4}\) |
