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 + 3b = 3b - 7y - 8 for b in terms of y.
| -\(\frac{2}{3}\)y + \(\frac{2}{3}\) | |
| 16y + 8 | |
| \(\frac{6}{11}\)y + \(\frac{1}{11}\) | |
| -1\(\frac{2}{3}\)y - 1\(\frac{1}{3}\) |
