Question

find the value of x :

7x + 9 = 23.
9x + 5 = 41.
23 = x + 8.
28 = 3x + 1.
8x - 2 = 46.
x + 3 = 2.​

Answer 1

Answer:

If a,b,c are in A.P

b=a+c/2

According to question 8x+4,6x−2,2x+7 are in A.P

6x−2=(8x+4+2x+7)/2

6x−2=10x+11/2

2(6x−2)=10x+11

12x−4=10x+11

12x−10x=11+4

2x=15

x=15/2=7.5
