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 = -b + 7x - 7 for b in terms of x.
| -\(\frac{15}{16}\)x - \(\frac{1}{2}\) | |
| \(\frac{1}{3}\)x + 1\(\frac{1}{6}\) | |
| 6x + 1\(\frac{1}{2}\) | |
| 2x + \(\frac{4}{5}\) |
