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 2b - 7b = -6b - 3x + 7 for b in terms of x.
| 2\(\frac{1}{2}\)x - 1\(\frac{1}{2}\) | |
| -9x + 7 | |
| \(\frac{1}{2}\)x + \(\frac{7}{8}\) | |
| \(\frac{3}{5}\)x + 1\(\frac{4}{5}\) |
