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