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 3c + 7c = c - 4z + 7 for c in terms of z.
| \(\frac{1}{4}\)z + 1\(\frac{1}{4}\) | |
| -\(\frac{1}{2}\)z + 3\(\frac{1}{2}\) | |
| -5\(\frac{1}{2}\)z + 3\(\frac{1}{2}\) | |
| \(\frac{1}{2}\)z - \(\frac{1}{12}\) |
