be
O
2
4
in
O​

Answer 1

Answer:

2

Step-by-step explanation:

x+2y=10. ( given, y= 6)

x+ 2( 6)=10

x+ 12= 10

x= 10-12

x= -2

Answer 2

The value of x = - 2

Given :

• The equation x + 2y = 10

• The value of y = 6

To find :

The value of x is

(1) - 2

(2) 2

(3) 4

(4) 5

Solution :

Step 1 of 2 :

Write down the given equation

Here the given equation is

x + 2y = 10 - - - - - - (1)

Step 2 of 2 :

Find the value of x

The value of y = 6

Putting y = 6 in Equation 1 we get

x + ( 2 × 6 ) = 10

⇒ x + 12 = 10

⇒ x = 10 - 12

⇒ x = - 2

Hence the correct option is (1) - 2

Correct question : If in the equation x + 2y = 10, the value of y is 6, then the value of x will be (1) -2 (2) 2 (3) 4 (4) 5
