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 = -3a - 8y - 1 for a in terms of y.
| -\(\frac{4}{5}\)y + \(\frac{1}{5}\) | |
| -2y - 1 | |
| -1\(\frac{6}{11}\)y - \(\frac{2}{11}\) | |
| y + \(\frac{1}{5}\) |
