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 + 4b = 4b - 8y - 4 for b in terms of y.
| -12y - 4 | |
| \(\frac{8}{9}\)y + 1 | |
| -\(\frac{2}{3}\)y - \(\frac{2}{3}\) | |
| -3y - 1 |
