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 -5b - b = -2b - 2y - 4 for b in terms of y.
| -\(\frac{9}{10}\)y - \(\frac{1}{5}\) | |
| \(\frac{1}{10}\)y - \(\frac{1}{5}\) | |
| \(\frac{1}{3}\)y + 1\(\frac{1}{3}\) | |
| \(\frac{5}{12}\)y - \(\frac{1}{12}\) |
