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 - 5b = 8b + 4y + 8 for b in terms of y.
| -1\(\frac{1}{4}\)y + 2\(\frac{1}{4}\) | |
| 2y - \(\frac{4}{7}\) | |
| -\(\frac{3}{4}\)y - \(\frac{2}{3}\) | |
| -\(\frac{1}{2}\)y - \(\frac{1}{2}\) |
