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 - 7b = 7b + 3y + 7 for b in terms of y.
| -\(\frac{3}{8}\)y - \(\frac{5}{8}\) | |
| -\(\frac{5}{8}\)y - \(\frac{7}{16}\) | |
| -1\(\frac{1}{4}\)y - 2\(\frac{1}{4}\) | |
| 1\(\frac{4}{5}\)y - \(\frac{3}{5}\) |
