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