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 - 3b = b + 9x - 4 for b in terms of x.
| 1\(\frac{1}{6}\)x + 1 | |
| -1\(\frac{1}{2}\)x + \(\frac{1}{2}\) | |
| -3x - 7 | |
| -\(\frac{1}{2}\)x - \(\frac{7}{8}\) |
