Question

3x - y = 2
5x - 2y = 1
solve by elimination method linear ​

Answer 1

Step-by-step explanation:

3x - y = 2 .....(1)

5x - 2y = 1 ......(2)

Multiply (1) by 2

6x - 2y = 4

5x - 2y = 1

Subtract them :-

x = 3

Substitute in (1)

9 - y = 2

-y = -7

y = 7

Therefore, x = 3, y = 7

Answer 2

Answer:

hope this helps u :-)

Step-by-step explanation:

3x - y = 2                           ...(i)

5x - 2y =1                           ...(ii)

 

2(3x - y = 2)

-->6x-2y=4

1(5x - 2y = 1

)-->5x-2y=1

                       -    +    -

                        ________

                         x=3

putting the value of x in equation ...(ii)

5x-2y=1

=>5(3)-2y=1

=>-2y=1-15

=>y=-14/-2

=>y=7

so, the value of x is 3 and value of y is 7
