2x + 3y =1/10
and 3x + 2y=1/8

​

Answer 1

Answer:

ok

Step-by-step explanation:

The cereal crops grown in India are shown. Select the correct option about correct order of

cereal crops grown maximum.

(1) Wheat (2) Jowar (3) Paddy

(A) 3, 1, 2 (B) 2, 3, 1 (C) 2, 1, 3 (D) 1, 3, 2

Answer 2

Use the elimination method to solve the system of equations :

2x + 3y = 1/10
3x + 2y = 1/8

Equation 1 is in the correct ax + by format .
Equation 2 is in the correct ax + by format .

Step 1 - Multiply Equation 1 by 3 :
3 * ( 2x + 3y = 1 / 10 ) -- > 6x + 9y = 0.3

Step 2 - Multiply Equation 2 by 2 :
2 * ( 3x + 2y = 1 / 8 ) -- > 6x + 4y = 0.25

Step 3 - subtract revised Equation 2 from revised Equation 1 :

6x + 9y = 0.3 - ( 6x + 4y = 0.25 )

9y - 4y = 0.3 - 0.25

Step 4 - simplify and solve for y :

5y = 0.05

y = 0.05/5

y = 0.01

Step 5 - now that we have solved for y , let's rearrange Equation 1 to solve for x:

2x = 0.1 - 3y

Divide each side by 2

2x /2 = 0.1 - 3y/2


x = 0.1 - 3y/2

Step 6 - we determined y = 0.01 .
Plug it into our rearranged equation 1 :

x = 0.1 - 3( 0.01 )/2

x = 0.1 - 0.03/2

x = 0.07/2

x = 0.035
