HELP! What is the value of X? WILL GIVE BRAINLIEST!

x =2

Step-by-step explanation:

Similar triangles:-

   Given diagram ΔABC  AND ΔDBE are similar triangles.

on simplification , we get

cross multiplication , we get

12x+6 =10x +10

12x-10x = 10 -6

 2x =4

  x =2

Therefore the value of x =2

verification:-

put x=2

both sides are equal

Therefore x value is 2

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
