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 7b + 4b = -8b - 2y - 7 for b in terms of y.
| -\(\frac{2}{5}\)y - \(\frac{7}{15}\) | |
| 2y - 3\(\frac{1}{2}\) | |
| -5\(\frac{2}{3}\)y + \(\frac{1}{3}\) | |
| \(\frac{1}{3}\)y - \(\frac{2}{3}\) |
