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