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 9b + 2b = -b - y - 7 for b in terms of y.
| -\(\frac{1}{11}\)y + \(\frac{7}{11}\) | |
| -\(\frac{13}{17}\)y + \(\frac{1}{17}\) | |
| -\(\frac{3}{10}\)y - \(\frac{7}{10}\) | |
| -1\(\frac{2}{3}\)y - \(\frac{5}{6}\) |
