Question

substitute 2x+2y=10;2x-3y=10​

Answer 1

Step-by-step explanation:

here, 2x+2y-2x+3y=20

5y=20,

y=4

Answer 2

Answer:

2x+2y=10………(i)

2x-3y=10………(ii)

From i ,

2(x+y) = 2(5)

x+y = 5

x = 5-y

substituting value of x in ii,

2(5-y)-3y = 10

10 -2y -3y =10

-5y = 0

y = 0/-5

y=0

substituting value of y,

x=5-y

x = 5
