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 -7b + b = 3b + 6y - 4 for b in terms of y.
| y - 5 | |
| \(\frac{7}{15}\)y + \(\frac{1}{3}\) | |
| \(\frac{3}{10}\)y - \(\frac{2}{5}\) | |
| -\(\frac{1}{2}\)y + \(\frac{2}{5}\) |
