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 -7b - 9b = -3b + 7x + 6 for b in terms of x.
| -7\(\frac{1}{2}\)x - 2 | |
| 7x - 7 | |
| -4x - 1\(\frac{1}{2}\) | |
| 3\(\frac{1}{3}\)x - 1 |
