Question

Please solve by Cross Multiplication Method
3x − 7y + 10 = 0 Y − 2x − 3 = 0

Answer 1

Answer:

GIVEN:

The equations are 3x-7y+10=0 and y-2x=3

TO FIND :

The values of x and y by using the Cross Multiplication Method.

SOLUTION :

Given  equations are 3x-7y+10=0 and y-2x=3

y-2x=3 can be written as

Now solving the equations by using the Cross Multiplication Method.

The formula for  Cross Multiplication Method is given by:

For equations  and  

, , , ,  and  

Substitute the values in formula,

Now equating  

∴ x=-1

Now equating  

∴ y=1

∴ the values are x=-1 and y=1.
