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 c - 7c = -c - 8z + 6 for c in terms of z.
| 1\(\frac{1}{3}\)z - 3 | |
| -\(\frac{1}{2}\)z + 3 | |
| 4\(\frac{1}{2}\)z - 4\(\frac{1}{2}\) | |
| -\(\frac{12}{13}\)z + \(\frac{7}{13}\) |
