MATHEMATICS System of Equations with Fractions HIGH SCHOOL CLASSROOM. In this video a system of equations with 2 unknowns is solved with fractions.
Exercise of system of equations with two unknowns, where we have a set of fractions for equation 1 and equation 2, it can be solved by several methods. This time we will carry it out:
X - 3/3 - Y - 4/4 = 0 Equation (1)
X - 4/2 - Y + 2/5 = 3 Equation (2)
It must first be simplified so that we obtain the equations in linear form.
Since we have a set of fractions in which we have different denominators, so we must apply the least common multiple between the fractions of 3 and 4 for equation (1) resulting in that the minimum would be 12, it divides the denominator of each fraction and the The result of that division, which would be the quotient, is multiplied by the numerator of each fraction.
