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 + 9b = b - 3y - 2 for b in terms of y.
| -1\(\frac{1}{8}\)y + \(\frac{5}{8}\) | |
| \(\frac{11}{15}\)y + \(\frac{4}{15}\) | |
| -1\(\frac{1}{3}\)y + \(\frac{2}{3}\) | |
| -2y - \(\frac{1}{3}\) |
