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 7b + 9b = b + 8x + 4 for b in terms of x.
| 4\(\frac{1}{4}\)x - 1\(\frac{1}{2}\) | |
| -\(\frac{1}{6}\)x + \(\frac{2}{3}\) | |
| -4x - 5 | |
| 1\(\frac{2}{3}\)x - \(\frac{1}{6}\) |
