Question

3x +7y =2 and 6x-5y=4. Solve by elimination method

Answer 1

Answer:

x = 2/3 & y = 0

Step-by-step explanation:

3x + 7y = 2............ 1eq.

6x + 7y = 4.............2nd eq.

Now multiply eq. 1st by 2

Then, 2(3x + 7y = 2) & 2nd by 1 then 1(6x + 7y = 4)

Now, 6x + 14y = 4.......3 eq.

6x + 7y = 4.........4 eq.

Now subtract eq. 3 and eq. 4

Then we eliminate the value of x and get the value of y = 0 & put the value in eq. 1 then we get the value of x = 2/3
