Given,
2x-34
+13
=0.
3x - 2y
+ 12
= 0​

Answer 1

Answer:

WE HAVE ,

 >> 2x-34+13=0      ....(1)

>> 3x-2y+12=0      ...(2)

Step-by-step explanation:

from 1 we get

 >>  2x = 21   >>  x = 21 / 2

 >> 10.5    

putting value of x in 2 we get,

 

   3(10.5 ) - 2y =-12

        31.5 -2y = -12

            2y = 43.5

             y = 21.75

hence,

       >>x =10.5

        >>y = 21.75  

i hope it helps.

Answer 2

let 2x-34+13=0 be equation 1.

let 3x-2y+12=0 be equation 2

from equation 1,

2x-34+13=0

2x-21=0

2x=21

x=21/2

x=10.5

put value of x in equation 2,

3x-2y+12=0

3(10.5)-2y=-12

31.5-2y=-12

-2y=-12-31.5

2y=-43.5

y=43.5/2

y=21.75

so the x is 10.5 and the y is 21.75
