If d is the midpoint of ce, ce=10x+18 and de=7x-1, find x

Given that D is the mid point of CE ,

So D will bisect CE, it means the length of DE and CD is equal.

=> DE + CD = CE

As DE and CD are equal,

=> DE + DE = CE

=> 2 DE = CE

Putting values from the question,

=> 2( 7x - 1 ) = 10x + 18

=> 14x - 2 = 10x + 18

=> 14x - 10x = 18 + 2

=> 4x = 20

=> x = 20 / 4

=> x = 10 / 2

=> x = 5



Therefore, the value of x is 5

Ithink not so sure but i tried it out and came out to be b
