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 4b - 8b = 8b + 2y + 2 for b in terms of y.
| -6\(\frac{1}{2}\)y - 1\(\frac{1}{2}\) | |
| \(\frac{1}{8}\)y - \(\frac{1}{2}\) | |
| 1\(\frac{1}{14}\)y - \(\frac{5}{14}\) | |
| -2\(\frac{1}{2}\)y - \(\frac{1}{2}\) |
