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 = -4b + 6x - 8 for b in terms of x.
| 1\(\frac{1}{8}\)x - \(\frac{1}{8}\) | |
| -\(\frac{9}{13}\)x + \(\frac{2}{13}\) | |
| -\(\frac{5}{7}\)x + \(\frac{5}{7}\) | |
| \(\frac{9}{11}\)x - \(\frac{8}{11}\) |
