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 -3b - 7b = 8b - 4y - 4 for b in terms of y.
| y - 2\(\frac{2}{3}\) | |
| \(\frac{1}{4}\)y + \(\frac{1}{2}\) | |
| -\(\frac{3}{11}\)y + \(\frac{4}{11}\) | |
| 1\(\frac{1}{2}\)y - \(\frac{9}{10}\) |
