Step-by-step explanation:

13x+11y=70 eq1

11x+13y=74 eq2

adding eq1 and eq2

24x+24y=144

dividing by 24

x+y=6 eq3

subtracting eq2 from eq1

2x-2x= -4

dividing by 2

x-y= -2 eq4

solving eq3 and eq4

x+y=6

x-y= -2

2x=4

x=2

substituting the value of x in eq3

x+y=6

2+y=6

y=6-2

y=4

x=2 y=4

விளக்கம்:

13 x+11 y=70                        .............................(1)

11 x+13 y=74                        .............................(2)

(1)+(2)=>24 x+24 y=144

x+y=6                                 ..............................(3)

(1)-(2) \Rightarrow x-y=-2            ...............................(4)

(3)+(4) ⇒  2 x=4

x=\frac{4}{2}=2

&x=2\end{aligned}

x-y=-2

2-y=-2 \Rightarrow-y=-2-2

-y=-4

y=4

எனவே தீர்வு (x, y)(2,4) ஆகும்.
