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 5b + 6b = -7b - 5x + 7 for b in terms of x.
| \(\frac{3}{5}\)x - \(\frac{2}{5}\) | |
| -\(\frac{11}{12}\)x + \(\frac{7}{12}\) | |
| 2\(\frac{1}{2}\)x - 3\(\frac{1}{2}\) | |
| 2\(\frac{2}{7}\)x - 1\(\frac{2}{7}\) |
