Question

10x + 5y = 25
4x - 5y = 3
What’s is the solution ??

Answer 1

the value of x is 2 and y is 1

Explanation:

10x + 5y =25

4x -5y =3

__________

14x = 28

x = 28/14

x =2

substitute the value of x in 10x + 5y =25,then we get

10*2+5y= 25

20 + 5y = 25

5y = 25-20

y = 5/5

y = 1

Answer 2

x=2, y=1

Explanation:

10x + 5y = 25

4x - 5y = 3

Add the two equations together to eliminate y

10x + 5y = 25

4x - 5y = 3

-------------------------

14x = 28

Divide by 14

14x/14 = 28/14

x = 2

Now find y

10x+5y = 25

10(2) +5y = 25

20+5y= 25

Subtract 20 from each side

5y = 25-20

5y = 5

Divide by 5

5y/5 = 5/5

y =1
