Reciprocal. Except that dividing by a rational equation is much easier.
2 x 41 = 82
When you multiply both sides by a negative number the inequality must be flipped over. You do not do that when multiplying by a positive number.
Any equation that requires division by four ninths.
87 = 3yDivide each side of the equation by 3:29 = y
That means that multiplying both sides of the equation by the same non-zero number is a valid operation, which often helps you simplify the equation.
By itself there is none. A coefficient is the multiplying factor in a polynomial equation.
