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 6b + 3b = 8b - 7y + 7 for b in terms of y.
| 5y - 3\(\frac{1}{2}\) | |
| -\(\frac{11}{14}\)y + \(\frac{1}{2}\) | |
| -\(\frac{1}{9}\)y + \(\frac{8}{9}\) | |
| 2\(\frac{3}{7}\)y + \(\frac{6}{7}\) |
