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