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 = -7b + 4x - 6 for b in terms of x.
| -1\(\frac{1}{6}\)x - \(\frac{1}{6}\) | |
| \(\frac{13}{14}\)x - \(\frac{3}{7}\) | |
| -11x + 8 | |
| 1\(\frac{3}{14}\)x - \(\frac{2}{7}\) |
