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 -4b + b = 9b - 2y + 7 for b in terms of y.
| 2\(\frac{2}{3}\)y - 1 | |
| -\(\frac{2}{11}\)y + \(\frac{6}{11}\) | |
| \(\frac{3}{13}\)y - \(\frac{7}{13}\) | |
| -y + 1\(\frac{1}{7}\) |
