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