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 - 4b = 5b + 7y + 2 for b in terms of y.
| -\(\frac{1}{2}\)y + \(\frac{1}{4}\) | |
| -\(\frac{11}{14}\)y - \(\frac{1}{7}\) | |
| -2\(\frac{1}{5}\)y + 1\(\frac{3}{5}\) | |
| -1\(\frac{2}{9}\)y + \(\frac{2}{3}\) |
