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