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 - 2b = b - 7y - 8 for b in terms of y.
| \(\frac{5}{9}\)y + \(\frac{8}{9}\) | |
| \(\frac{1}{13}\)y + \(\frac{7}{13}\) | |
| y + \(\frac{1}{4}\) | |
| 4\(\frac{1}{2}\)y - 4\(\frac{1}{2}\) |
