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 + 9c = 7c - 8y + 3 for c in terms of y.
| -\(\frac{3}{14}\)y + \(\frac{1}{14}\) | |
| -\(\frac{1}{16}\)y + \(\frac{1}{8}\) | |
| 3\(\frac{2}{5}\)y - \(\frac{3}{5}\) | |
| -1\(\frac{1}{4}\)y + 1\(\frac{1}{8}\) |
