11
The answer is 11

Answer 2

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,

$10(\frac{4}{5})+3$

=11

Answer: option third, 11
