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 + 6b = 3b + 5y + 9 for b in terms of y.
| \(\frac{1}{6}\)y - \(\frac{1}{6}\) | |
| \(\frac{1}{10}\)y + \(\frac{2}{5}\) | |
| \(\frac{1}{7}\)y + \(\frac{9}{14}\) | |
| -\(\frac{1}{4}\)y + 2\(\frac{1}{4}\) |
