Answer 2

Concept:

Cross multiplication is the process of multiplying the numerator of one fraction by the denominator of another and the numerator of another fraction by the denominator of the first.

Given:

Two equations 4x+6y=5 and 2x+9y=3

Find:

We have to find the value of x and y by solving the equation with cross multiplication

Solution:

We have two equations:

4x+6y=5

2x+9y=3

By cross multiplication method multiply 4 in second equation and 2 in first equation so that to make value of "x" same:

(4x+6y=5 ) x 2

(2x+9y=3) x 4

so,

8x+12y=10

8x+36y=12

Subtract both equations :

24y = 2

  y = 1/12

Put the value of y in the equation to get the value of x:

2x + 9/12= 3

2x= 3- 3/4

 2x= 9/4

    x= 9/8

Hence the value of  x= 9/8 and y = 1/12.
