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 2c + 7c = -c + 3z - 6 for c in terms of z.
| 5z + 8 | |
| \(\frac{1}{3}\)z + \(\frac{1}{9}\) | |
| -1\(\frac{1}{3}\)z - 2 | |
| -2\(\frac{1}{5}\)z + 1 |
