Question

x + y = 4; x - y = 2. solve by elimination method
​

Answer 1

Answer:

x = 3 and y = 1

Step-by-step explanation:

x + y = 4 --------- ( i )

x - y = 2 ----------( ii )

now adding eq (i) & (ii) we get,

2x = 6

=> x = 3

now put x = 3 in eq (i) we get,

3 + y = 4

=> y = 4 - 3 = 1

Hence, x = 3 , y = 1

Answer 2

Answer:

by arranging the equation x=3 and y=1

Step-by-step explanation:

x+y=4

x-y=2

2x=6

x=6 upon 2=3

use the first original equation to find y

x+y=4

3+y=4

y=4-3

y=1
