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 + 9b = 4b - 6y + 4 for b in terms of y.
| 3y - 2 | |
| y + 1 | |
| 1\(\frac{2}{13}\)y - \(\frac{4}{13}\) | |
| \(\frac{4}{5}\)y - \(\frac{9}{10}\) |
