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 -9b + 6b = 3b - 9y - 9 for b in terms of y.
| \(\frac{8}{11}\)y + \(\frac{1}{11}\) | |
| \(\frac{8}{11}\)y + \(\frac{2}{11}\) | |
| 1\(\frac{7}{8}\)y - 1\(\frac{1}{8}\) | |
| 1\(\frac{1}{4}\)y + \(\frac{3}{4}\) |
