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 -3a - 6a = 7a - 7y + 3 for a in terms of y.
| \(\frac{1}{10}\)y - \(\frac{3}{10}\) | |
| -3\(\frac{1}{2}\)y + 1 | |
| \(\frac{1}{13}\)y - \(\frac{7}{13}\) | |
| \(\frac{1}{6}\)y + \(\frac{5}{12}\) |
