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 9b + 2b = -4b - 4y + 2 for b in terms of y.
| -1\(\frac{1}{2}\)y - 1\(\frac{1}{2}\) | |
| 7y - \(\frac{1}{2}\) | |
| \(\frac{7}{16}\)y - \(\frac{5}{16}\) | |
| -\(\frac{6}{13}\)y + \(\frac{2}{13}\) |
