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