We are given an equation here:


5x+6=10

Step 1:

Find the value of x, solving the given equation


5x+6=10

Here 6 is in addition of left side, so we apply opposite operation of addition, subtracting 6 from right side,


5x=10-6


5x=4

Here 5 is in multiplication on left side, so dividing right side by 5,

x= 4/5

Step 2:

Plug the value of x in the expression 10x+3.

So replacing x by 4/5 in the given expression we have,


10((4)/(5))+3

=11

Answer: option third, 11
