Answer 2

Answer: 11  (Option C)

Step by step explanation:

If 5x+6=10

value of 10x+3 = ?

Step 1 : solve the first equation to find the value of x

5x + 6 = 10

5x = 10 – 6

5x = 4

X = 4/5

Step 2 : Susbitute the value of x in the second equation

10x + 3 = ?

10 ( 4/5) + 3  

= 40 / 5 + 3

= 40 + 15 /5 (Taking L.C.M)

= 55 / 5

= 11
