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