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