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 - 5b = -8b - 7y + 4 for b in terms of y.
| -\(\frac{2}{7}\)y + \(\frac{4}{7}\) | |
| -7y + 3\(\frac{1}{2}\) | |
| -\(\frac{6}{17}\)y + \(\frac{7}{17}\) | |
| -\(\frac{1}{4}\)y + \(\frac{3}{4}\) |
