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 - 4a = 5a + 8y + 2 for a in terms of y.
| -\(\frac{1}{5}\)y - \(\frac{3}{5}\) | |
| y + \(\frac{3}{13}\) | |
| -5\(\frac{1}{3}\)y + 1\(\frac{2}{3}\) | |
| -2y - \(\frac{1}{3}\) |
