Question

solve the equation by elimination method 2x +y =6 ;4x -2y =4​

Answer 1

Answer:

2x +y -6=0 ----(1)

4x -2y-4=0-----(2)

2×(1) = 4x +2y -12 =0 ------(3)

1×(2) = 4x -2y -4=0 ------(4)

(3) -(4)

4x-4x +2y+2y-12+4=0

4y -8=0

y =8/4

y =2

Putting y=2 in (1)

2x +2 =6

x=6-2/2

x=2

Therefore x=2,y=2

Answer 2

Step-by-step explanation:

Given 2x + y =6_(1)

4x-2y=4_(2)

(1)×2

=4x +2y=12

add (1) and(2)

=8x=16

x=2

substituting x in (1) or (2)

y=2
