Answer:
The equivalent equation is 1) 2x - 4y = 8
Step-by-step explanation:
The given equation is x - y = 8.
Here we have 8 on the right hand side.
Now find the equation which has 8 on the right hand side.
It is 2x - 4y = 8
Therefore, the equivalent equation is 1) 2x - 4y = 8
Now let's find the value of x and y.
From the equation x - y = 8, we get
x = y + 8
Now plug in x = y + 8 in the equation 2x - 4y = 8
2(y + 8) -4y = 8
Use the distributive property
2y + 16 -4y = 8
-2y + 16 = 8
-2y = 8 -16
-2y = -8
Dividing both sides by -2, we get
y = 4
Now plug in y = 4 in x = y + 8 to get the value of x.
x = 4 + 8 = 12
So the value of x = 12 and y = 4
If we plug these values in the above two equations, we get will get 8.
