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 - 3c = 7c + 7y - 7 for c in terms of y.
| -\(\frac{3}{5}\)y + 1\(\frac{4}{5}\) | |
| 2y - \(\frac{5}{6}\) | |
| -\(\frac{2}{3}\)y - \(\frac{3}{4}\) | |
| -1\(\frac{1}{4}\)y + \(\frac{7}{8}\) |
