0:06 13:13 Each side by the multiplicative inverse of the fraction. So here in 3 X 3 is the coefficient X isMoreEach side by the multiplicative inverse of the fraction. So here in 3 X 3 is the coefficient X is the variable. So letter A solve 3/4 C equals 18 to solve this I'm just going to rewrite.

A rational equation is an equation that contains fractions with xs in the numerator, denominator or both. Here is an example of a rational equation: (4 / (x + 1)) - (3 / (x - 1)) = -2 / (x^2 - 1). Let's think back for a moment about solving an equation with a fraction. 1/3 x = 8.

So divide both sides by zero point four or five. Those go away. And we get sevenMoreWhich is division. So divide both sides by zero point four or five. Those go away. And we get seven letter B point seven is the coefficient. So divide both sides by 0.7.

And over here I haveMoreSo I'm going to add 17.5 to both sides. So here that cancels I'm left with y. And over here I have 11 Plus 17.5. Now you have to line up the decimals. And you're saying well 11 doesn't have a decimal.

In simple words, the coefficient is defined as the number or term multiplied by the variable. In the case of the rational coefficient, the coefficient multiplied by the variable must be in the form of a fraction. Here, ⅔ is the rational coefficient of x.

1:24 4:42 Since we ended with a variable equal to a constant there is only one solution to this equation.MoreSince we ended with a variable equal to a constant there is only one solution to this equation. Let's look at a second. Example this equation also has some distributing that can be done on the left.

0:24 13:47 Straight down 5 plus 2 is 7 8. Plus 3 is 11. So remember it's negative negative eleven.MoreStraight down 5 plus 2 is 7 8. Plus 3 is 11. So remember it's negative negative eleven.

You're always going to divide bothMoreSo anytime you solve an equation with a rational coefficient. You're always going to divide both sides. So let's remember that anytime.

Rational Coefficient: A coefficient is a number in front of a variable. A rational coefficient is in front of a variable and a rational number - so it could be an integer, decimal, or fraction.
