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