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 5b - 9b = -9b - 3y + 6 for b in terms of y.
| -4y - 1 | |
| y + 7 | |
| \(\frac{3}{7}\)y + \(\frac{3}{7}\) | |
| -4y - 4\(\frac{1}{2}\) |
