Question

3x-4y=14,2x-2y=0 by elimination method

Answer 1

Answer:

x= -14 and y= -14.

Step-by-step explanation:

given 3x-4y=14 and 2x-2y=0.

now from 2x-2y=0 we can get x=y.

putting the value

3y-4y=14

or y= -14.therefore x=-14.

Answer 2

Answer: x=-14 and y=-14

Step-by-step explanation:

Multiply 3x-4y=14 with 2

So that will become, 6x-8y=28 -----(1)

Then multiply 2x-2y=0 with 3

Which is, 6x-6y=0--------(2)

Now, subtract (2) from (1)

                6x  -   8y   = 28

            (-) 6x - (+)6y  = (-)0

             ______________

                0x  -2y   = 28

∴y =-14

now from (2) ====>  x=2y/2 =====> x=y

Hence x is also -14

Thank you, hari om!
