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 - 8b = 2b + y - 1 for b in terms of y.
| \(\frac{1}{6}\)y + \(\frac{5}{6}\) | |
| -y + \(\frac{1}{9}\) | |
| -\(\frac{7}{9}\)y + \(\frac{8}{9}\) | |
| \(\frac{5}{8}\)y - \(\frac{1}{4}\) |
