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 -7b - 6b = 6b + y - 9 for b in terms of y.
| y - 1\(\frac{1}{5}\) | |
| -\(\frac{3}{4}\)y - \(\frac{2}{3}\) | |
| -\(\frac{7}{13}\)y + \(\frac{9}{13}\) | |
| -1\(\frac{1}{8}\)y - \(\frac{1}{4}\) |
