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