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 -4b - 2b = -9b - y - 8 for b in terms of y.
| \(\frac{2}{3}\)y - \(\frac{2}{9}\) | |
| \(\frac{1}{5}\)y - 1\(\frac{3}{5}\) | |
| -\(\frac{1}{7}\)y + \(\frac{4}{7}\) | |
| -\(\frac{7}{15}\)y - \(\frac{2}{15}\) |
