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