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