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 = 7b - 9y + 7 for b in terms of y.
| \(\frac{6}{13}\)y + \(\frac{2}{13}\) | |
| \(\frac{7}{16}\)y - \(\frac{7}{16}\) | |
| -2\(\frac{3}{5}\)y - \(\frac{3}{5}\) | |
| y - 3\(\frac{1}{2}\) |
