Question

solve the following pair of linear equation 3 X + 2 Y=11, 5 x minus 2 Y =13​

Answer 1

Answer:

X=2 and Y =1

Step-by-step explanation:

3X+2Y=11_____________EQ1 (Add them )

5X-2Y=13_____________EQ2

8X=24

X=24÷8

X=3

Sustitute X=3 in any of the given equations

suposse u substitute it in 1st equation

3×3+2Y=11

9+2Y=11

2Y=11-9

2Y=2

Y=1

Therefore X=3 and Y=1

Answer 2

Answer:

3x+2y=11. (1)

5x-2y=13. (2)

Multiply equation( 1) by 5 and equation( 2) by 3

15x+10y=55

15x-6y=39

By elimination method

15x+10y=55

15x-6y=39

(-) (+) (-)

___________

16y=16

y=16/16

y=1

Now,put the value of y in equation 1

3x+2y=11

3x+2(1)=11

3x=11-2

3x=9

x=9/3

x=3

Hence, the value of x is 3 and the value of y is 1
