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