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