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