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