Question

3x - 4y = 6 and 3x - y = 9 please solve the equation by elimination method​

Answer 1

Answer:

x=10/3 and y=1

Step-by-step explanation:

3x - 4y = 6 -----(1)

3x - y = 9 ----(2)

Multiply equation (2) by 4

3x - 4y = 6 -----(1)

12x - 4y = 36 ----(3)

Now subtract (3) - (1)

x=10/3

Substitute x in (2)

10-y=9

y=1

Answer 2

Step-by-step explanation:

3x-4y=6. 3x-y=9

3x-4y-3x+y=-3

-3y=-3

y=1

putting the value of y in equation.1

3x -4×1=6

3x-4=6

3x=6+4=10

×=10/3
