Sum of the roots of the equations
(6x+5)/2= 3, (3x+10)/4 = 5 is

OPtion

1) 5/16
2) 5/9
3) 3/13
4) 7/2
5) 4/15
6) 5/13
7) 9/2
8) 11/8
9) 13/3
10) 5/6

Solution

(6x+5)/2= 3 implies that x = 1/6
(3x+10)/4 = 5 implies that x = 10/3
Sum of roots = 7/2

Correct Option: 4 Best Solution (19)

SHUBHAM   13 years AGO

6x +5=6
therefore x =1/6
3x +10=20 therefore x=10/3
adding we get 27/6

KALPANA G   13 years AGO

(6x+5)/2= 3==>6x+5=6==>x=1/6,
(3x+10)/4 = 5==>3x+10=20==>x=10/3,
Therefore sum of the roots the equations=1/6+10/3=7/2

6x+5=6
3x+10=20
find the value of x for both the cases then take sum of root of both the values of x

Raushan Kumar   13 years AGO

(6x+5)/2= 3
6x+5=6
6x=1
x=1/6


(3x+10)/4 = 5
3x+10=20
3x=10
x=10/3


sum of roots=1/6 +10/3= (1+20)/6=21/6=7/2

so ans is option 4

HARMEET KAUR   13 years AGO

(6x+5)/2= 3,
x= 1/6

(3x+10)/4 = 5
x=10/3

sum of 1/6 and 10/3=21/6 or 7/2

Dr.Dipin Singh   13 years AGO

(6x+5)/2= 3, 6x+5=6; x=1/6


(3x+10)/4 = 5; 3x+10=20; x= 10/3
so 1/6 +10/3 = 21/6 = 7/2

dhiresh   13 years AGO

first eq is (3x+5)/2=3 =>3x=6-5 =>x=1/6
second eq is (3x+10)/4=5 =>3x=20-10 =>x=10/3
1/6+10/3=7/2
so opion 4 is the answer.

SUDESHNA SEN   13 years AGO

(6x+5)/2=3 => x= (1/6)
(3x+10)/4=5 => x= (10/3)
So, (1/6)+(10/3)= (21/6) or, (7/2)..... Option 4)

Sneha Latha M   13 years AGO

From first equation we can get the root as 1/6
From second equation we can get the root as 10/3
By adding the two roots we can get 7/2
