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 -4c + 6c = 2c - 4y + 1 for c in terms of y.
| -\(\frac{1}{10}\)y + \(\frac{7}{10}\) | |
| 1\(\frac{2}{3}\)y - \(\frac{1}{6}\) | |
| 1\(\frac{1}{2}\)y - \(\frac{1}{4}\) | |
| \(\frac{3}{10}\)y - \(\frac{1}{2}\) |
