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
