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 - 7b = 9b - x + 8 for b in terms of x.
| -\(\frac{6}{13}\)x - \(\frac{8}{13}\) | |
| -4x + 4 | |
| \(\frac{7}{18}\)x - \(\frac{7}{18}\) | |
| 4x + 1 |
