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 6b - 4b = 9b - 7y - 4 for b in terms of y.
| y + 1\(\frac{1}{3}\) | |
| \(\frac{2}{11}\)y + \(\frac{2}{11}\) | |
| -\(\frac{1}{3}\)y - \(\frac{2}{9}\) | |
| -11y + 4 |
