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