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 + 4c = -7c - 2z + 2 for c in terms of z.
| -\(\frac{2}{3}\)z + \(\frac{2}{9}\) | |
| z + \(\frac{1}{7}\) | |
| -z - 5 | |
| 3z - \(\frac{1}{2}\) |
