Question

X-4y+14=0 and 3x+xy-14 =0. Solve it by alimination method

Answer 1

Answer:

x = 2, y = 4

Step-by-step explanation:

Given equations are

x - 4y + 14 = 0 ---------(1)

3x + 2y - 14 = 0 ---------(2)

By Cancellation Method :

Now do like this

eqn(1)*(1)=> x - 4y + 14 = 0

eqn(2)*(2)=> 6x + 4y -28 = 0

---------------------------

7x - 14 = 0

--------------------------

=> 7x = 14

=> x = 14/7

=> x = 2

Therefore x = 2

Now substitute x = 2 in x - 4y + 14 =0

=> 2 - 4y + 14 =0

=> 4y = 16

=> y = 16/4

=> y = 4

Therefore y = 4

The values of x = 2,y = 4
