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 + 4b = 8b - 7x - 9 for b in terms of x.
| 1\(\frac{5}{6}\)x + 1\(\frac{1}{2}\) | |
| -\(\frac{3}{11}\)x + \(\frac{9}{11}\) | |
| x + \(\frac{3}{5}\) | |
| -\(\frac{3}{10}\)x + \(\frac{3}{5}\) |
