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 5b + 2b = 4b - 9y - 8 for b in terms of y.
| -1\(\frac{3}{4}\)y - 1\(\frac{1}{2}\) | |
| -2y - \(\frac{1}{5}\) | |
| 3\(\frac{1}{2}\)y + 4 | |
| -11y - 8 |
