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