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