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 -8b - 3b = 2b + 4y - 9 for b in terms of y.
| y + \(\frac{4}{17}\) | |
| \(\frac{4}{5}\)y + \(\frac{2}{15}\) | |
| 1\(\frac{3}{5}\)y + 1 | |
| -\(\frac{7}{10}\)y + \(\frac{9}{10}\) |
