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 8b - 2b = 7b - 9x - 9 for b in terms of x.
| -3x - 8 | |
| \(\frac{5}{7}\)x + \(\frac{6}{7}\) | |
| -11x + 7 | |
| -7x - 9 |
