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