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 + 6x - 9 for b in terms of x.
| -\(\frac{7}{8}\)x + \(\frac{3}{8}\) | |
| -\(\frac{11}{15}\)x + \(\frac{3}{5}\) | |
| \(\frac{1}{5}\)x - 1\(\frac{2}{5}\) | |
| 1\(\frac{1}{3}\)x + 1 |
