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 b + 2b = 4b + 8y + 5 for b in terms of y.
| -2y - 1\(\frac{2}{3}\) | |
| -\(\frac{3}{17}\)y + \(\frac{9}{17}\) | |
| -2y + 1 | |
| 12y + 4 |
