Question

Solve by cross multiplication method:

3x – 7y +10 = 0

y – 2x =3​

Answer 1

Answer: The values are x=-1 and y=1.

Step-by-step explanation:

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.
