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