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 + 9c = -4c - 3y + 5 for c in terms of y.
| -1\(\frac{2}{3}\)y + 1 | |
| -2\(\frac{2}{5}\)y + 1 | |
| \(\frac{5}{8}\)y + \(\frac{3}{8}\) | |
| -\(\frac{9}{10}\)y + \(\frac{3}{5}\) |
