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 8b + 4b = 7b - 3x - 5 for b in terms of x.
| x - \(\frac{2}{5}\) | |
| -7x - 5 | |
| -x + 5 | |
| x - \(\frac{7}{12}\) |
