Question

Qn. Simultaneous equations - elimination method
3x-2y=7
4x+y=13


Pls ans short and precisely.

Answer 1

Answer:

x=3 and y=1

Step-by-step explanation:

equation 1---> 3x-2y = 7

equation 2---> 4x+y = 13

in equation 2, multiplying both sides by 2, we get

8x+2y = 26

Now, By adding equation 1 to equation 2,we get

3x - 2y + 2y + 8x = 26+7

11x = 33

x = 3

Putting value of x in equation 2, we get

4x3 + y = 13

12 + y = 13

y = 1

So, x=3 and y=1
