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