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