Question

(3) 4x + 5y = 3, 12x + 25y = 11​

Answer 1

Step-by-step explanation:

4x+5y = 3 _eq1

12x+25y= 11 _eq2

multiply eq1 with 3

12x+15y=9

12x+25y=11 (sub)

-10y = -2

y= -2/-10

y= 1/5

12x+25(1/5)=11

12x+5 = 11

12x= 11-5

12x=6

x = 1/2

Answer 2

Answer:

x=1/2;y=1/5

Step-by-step explanation:

4x + 5y = 3 __(i)

12x + 25y = 11 __(ii)

By multiplying equation (i) by 3 we get,

12x + 15y = 9 __(iii)

Subtracting (iii) from (ii)

10y = 2

Therefore y = 1/5

Putting the value of y in equation (i) we get

4x + 1 = 3

4x = 2

Therefore x = 1/2.
