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 6b + 9b = -4b + 8x + 7 for b in terms of x.
| 11x + 3 | |
| \(\frac{1}{8}\)x - 1\(\frac{1}{8}\) | |
| -\(\frac{1}{10}\)x + \(\frac{7}{10}\) | |
| \(\frac{1}{13}\)x + \(\frac{7}{13}\) |
