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