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