Question

sublimation method of class 10 solve this question 4x-3y+11=0 and 5x+4y +37=0​

Answer 1

Step-by-step explanation:

4x-3y = -11 ------i)

5x+4y= -37 -----ii)

Now,

16x-12y = -44 (multiplying ( i) with 4 )

15x+12y= -111 (multiplying ( ii) with 3)

------------------------

31x = -155

so, x= -155÷31

x= -5

and (4×-5 ) +11 = 3y

3y = -20+11

y= -9÷3 = -3
