Question

3x-2y=4;6x+7y=19 equation in two variable​

Answer 1

Answer:

y = 1

x = 2

Step-by-step explanation:

3x - 2y = 4 -1

6x + 7y = 19 -2

multiplying 2 in equation 1 we get :

6x - 4y = 8 -3

now subtract eq. 3 from eq. 2

we get

11y = 11

so, y = 1 and put y = 1 in eq. 1

we get x = 2

Hope u understood the answer.

Answer 2

Step-by-step explanation:

3x-2y=4 -1

6x+7y=19 -2

multiply 2 in equation 1

6x-4y=8

now subtract equation 3 from equation 2

we get

11y=11

so, y=1 and put y=1 in eq 1

we get x=2
