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 + 3b = -9b - 7x - 8 for b in terms of x.
| \(\frac{3}{10}\)x + \(\frac{1}{5}\) | |
| \(\frac{7}{13}\)x + \(\frac{2}{13}\) | |
| -6\(\frac{1}{2}\)x + 1\(\frac{1}{2}\) | |
| -1\(\frac{1}{4}\)x - 1 |
