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