Answer:
The answer is x=2 and y=0.
Explanation:
The given Equations are:
5x-2y=10 ----------------- (i)
4y+20=10x ----------------- (ii)
From equation find the value of x, that is:
5x=10+2y (Obtained By adding 2y on both side of Equation (i))
Next divide with 5 on both side to get x:
x=(10+2y)/5 ------------------ (iii)
Put this value of x in equation (ii):
4y+20=10((10+2y)/5)
Simplifying the above equation:
4y+20=2(10+2y)
4y+20=20+4y
From the above equation the solution of y is not possible.
We can make it 0. So,
y=0
Put this value of y in equation (iii), to get value of x:
x=(10+2(0))/5
x=(10+0)/5
x=10/5
x=2
