Question

find the solution of the following linear equation
x+y= 3 , 4x-2y = 0​

Answer 1

Answer:

x = 1, y = 2

Step-by-step explanation:

2x+2y = 6 (Multiply x+y=3 with 2)

4x-2y = 0

by elimination method, adding both equations, we get

6x=6

x=1

2+2y=6

2y=4

y=2

Answer 2

Let's take the value of x be 1,

x+y = 3

1+y= 3

y = 3-1

y = 2

4x-2y=0

4*1-2*2 = 0

4-4 = 0

As the solution (1,2) satisfies both the conditions, it is the solution of this linear equation.
