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