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