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 -4b - 8b = 6b - x - 4 for b in terms of x.
| -\(\frac{7}{10}\)x + \(\frac{2}{5}\) | |
| x + 5 | |
| -2\(\frac{1}{3}\)x + 1\(\frac{1}{3}\) | |
| 1\(\frac{5}{8}\)x + 1\(\frac{1}{8}\) |
