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