Question

Solve the following pair of linear equations :
3x + 2y = 11
5x - 2y = 13

Answer 1

Answer:

Plz hit the thank

Step-by-step explanation:

Let 3x + 2y = 11............ Equation (1)

And 5x - 2y = 13................ Equation (2

On adding eq (1) and (2)

We get

3x + 2y = 11

5x - 2y = 13

= 8x = 24

= x = 3

Now put in eq (1)

3(3) +2y = 11

9 + 2y = 11

2y = 2

y = 1

So value of x=3

y =1

Answer 2

Answer:

y=1 x=3

Step-by-step explanation:

3x+2y=11 -eq1

5x - 2y = 13 -eq2

On adding eq1 and 2

3x+2y+5x - 2y=11+13

8x=24

x=24/8

x=3

substitute the value of x in eq 1

3x + 2y = 11

(3×3)+2y= 11

9+2y= 11

2y= 11-9

2y=2

y=2/2

y=1
