Required
Get matching coefficient for elimination
The coefficient of x in both expressions are factors.
So, we can multiply the second equation by 2 to get the coefficient of x in the first.
i.e.
So, the system becomes:
<em>Now, x can be eliminated</em>
Answer:
Option D that is y=-2(x+1) is the correct choice.
Explanation:
Given equation:
We have to find another equation which has only one solution.
Standard form of equation:
Condition for one solution.
We have to arrange other equation in the form of
Mark all the options as a,b,c and d.
Now from the above options we can see that option are not providing the desired result.
So
can be obtained from the last option.
As
Option D that is is the equation from where we can obtained only one solution.
