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 b - 2b = 8b + 6y - 7 for b in terms of y.
| -1\(\frac{1}{7}\)y + 1 | |
| -\(\frac{2}{13}\)y + \(\frac{9}{13}\) | |
| -\(\frac{9}{17}\)y - \(\frac{7}{17}\) | |
| \(\frac{7}{12}\)y - \(\frac{1}{4}\) |
