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 + 7b = 8b + 8y - 1 for b in terms of y.
| \(\frac{1}{2}\)y + \(\frac{1}{3}\) | |
| -\(\frac{1}{9}\)y + \(\frac{1}{9}\) | |
| 6\(\frac{1}{2}\)y - 4 | |
| -\(\frac{1}{5}\)y + \(\frac{3}{10}\) |
