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 -3c + 6c = 9c + 5y - 7 for c in terms of y.
| 2\(\frac{3}{4}\)y + 1\(\frac{3}{4}\) | |
| \(\frac{1}{12}\)y + \(\frac{7}{12}\) | |
| \(\frac{3}{8}\)y + \(\frac{5}{8}\) | |
| -\(\frac{1}{4}\)y - \(\frac{3}{4}\) |
