Verified Answer :

\(5x+6=10\)
\(5x=10-6\)
\(5x=4\)
\(x=4/5\)

If we substitute the value of x into the second equation

\(10x+3\)
\(10\times 4/5+3\)
\(8+3=11\)
Therefore, your solution is 11

Answer: 11

Step by step explanation:


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 : Substitute the value of x in the second equation


10x + 3 = ?

10 ( 4/5) + 3  

= 40 / 5 + 3

= 40 + 15 /5

= 55 / 5

= 11
