1. 15
2. 12
3. 18
4. 10​

Answer 1

Answer:

12

Step-by-step explanation:

Answer is 12 (B)Explanation:Let us multiply equation one with 3that is 3*((2x-y)=4)we will get 6x-3y=12.so compare the above equation with 2nd equation that is 6x-3y=?so,the answer is 12.

Answer 2

SOLUTION

TO CHOOSE THE CORRECT OPTION

If (2x-y) = 4 then (6x-3y) =

1. 15

2. 12

3. 18

4. 10

EVALUATION

PROCESS : 1

Here the given equation is

$\displaystyle \sf{ (2x - y) = 4}$

Multiplying both sides by 3 we get

$\displaystyle \sf{ \implies 3 \times (2x - y) = 3 \times 4}$

$\displaystyle \sf{ \implies (6x -3 y) = 12}$

PROCESS : 2

Here the given equation is

$\displaystyle \sf{ (2x - y) = 4}$

Now

$\displaystyle \sf{ (6x -3 y) }$

$\displaystyle \sf{ = 3 \times (2x - y) }$

$\displaystyle \sf{ = 3 \times 4 }$

$\displaystyle \sf{ = 12}$

FINAL ANSWER

Hence the correct option is 2. 12
