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
