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