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 8c + 2c = 4c - 8z + 6 for c in terms of z.
| 3z - 1 | |
| 7z - 1 | |
| -2\(\frac{1}{2}\)z + 1\(\frac{1}{2}\) | |
| -\(\frac{1}{7}\)z + \(\frac{3}{14}\) |
