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 -8b - 6b = -2b - 3x + 9 for b in terms of x.
| -\(\frac{3}{4}\)x + \(\frac{1}{2}\) | |
| -\(\frac{1}{2}\)x - 1\(\frac{1}{2}\) | |
| x + 4\(\frac{1}{2}\) | |
| -15x + 9 |
