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 + 5b = 8b + 7x - 9 for b in terms of x.
| -\(\frac{2}{15}\)x + \(\frac{3}{5}\) | |
| \(\frac{1}{6}\)x + \(\frac{7}{12}\) | |
| x + \(\frac{3}{5}\) | |
| -14x + 6 |
