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 -8b + 9b = -6b - 6y - 4 for b in terms of y.
| y + \(\frac{1}{2}\) | |
| \(\frac{4}{15}\)y + \(\frac{1}{15}\) | |
| \(\frac{3}{8}\)y + \(\frac{7}{8}\) | |
| 7\(\frac{1}{2}\)y + 2 |
