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 -b + 9b = 8b + 3y + 4 for b in terms of y.
| \(\frac{2}{3}\)y - \(\frac{4}{9}\) | |
| -1\(\frac{5}{11}\)y + \(\frac{7}{11}\) | |
| -\(\frac{4}{9}\)y - \(\frac{1}{9}\) | |
| 4\(\frac{1}{4}\)y + 2\(\frac{1}{4}\) |
