Question

2x+y=10 and 2x-y=2 elimination​

Answer 1

Answer:

2x + y = 10 --------(I)

2x - y  = 2 ---------(II)

Adding (I) and (II), we get

2x+2x+y-y = 10 - 2

4x = 8

x = 2

From equation (I), y = 10 - 2x

y = 10 - 4

y = 6

Hence x = 2 and y = 6

Answer 2

Step-by-step explanation:

2x+y=10-----(1)

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

adding both equation

2x+y=10

2x-y=2

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

4x=12

X=3

put X=3 in equation (1)

2x+y=10

2(3)+y=10

6+y=10

y=10-6

y=4
