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 8b + 7b = -4b - 3y + 9 for b in terms of y.
| 2y - 1\(\frac{1}{3}\) | |
| -13y - 5 | |
| 2y - 4\(\frac{1}{2}\) | |
| -\(\frac{5}{6}\)y + \(\frac{3}{4}\) |
