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 + 8b = -6b - 7y - 7 for b in terms of y.
| -2\(\frac{2}{7}\)y - 1\(\frac{1}{7}\) | |
| -\(\frac{2}{5}\)y + \(\frac{3}{5}\) | |
| -3y - 1\(\frac{2}{5}\) | |
| -16y - 9 |
