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 -7c + 7c = 3c + y + 9 for c in terms of y.
| \(\frac{3}{5}\)y - \(\frac{9}{10}\) | |
| 1\(\frac{1}{3}\)y - 2\(\frac{1}{3}\) | |
| -\(\frac{5}{8}\)y + \(\frac{3}{16}\) | |
| 2\(\frac{1}{6}\)y + \(\frac{2}{3}\) |
