Answer:
1) Solution (2,-3)
2) Solution (-1, )
3) Solution ()
Step-by-step explanation:
We need to solve equations using elimination
1)
Let:
Adding both equations:
We get value of x = 2
Now, put value of x into equation 1 to find value of y
So, we get y = -3
Solution (2,-3)
2)
Let:
Adding both equations
We get: y= -3/2
Now find value of x by putting value of y in eq(1)
We get x = -1
Solution (-1, )
3)
let:
Add both equations:
We get x = -1/2
Now, put value of x in equation 2
We get y = -5/2
Solution ()
The standard form of a linear equation in general is given by:
Now we are given the equation :
In order to convert this into standard equation, we have to eliminate the 3 in the second term on the left side of equation.
Here 3 is in division ,so we have to perform opposite operation of division that is multiplication.
So multiplying both sides by 3 , we have
So that means option A.Multiply both sides of the equation by 3. The standard form of the equation is 12x – 2y = 24. is the correct advice given by Sofiya.
