$y = 13$ $y=13$

$2 x$ $2x$ in this equation is the same as saying $2$ $2$ times $x$ $x$ , so where there is $a n$ $an$ $x$ $x$ , you put a $5$ $5$ there.

So you get this

$y = 2 (5) + 10$ $y = 2(5)+10$

Then

$10 + 3 = 13$ $10+3=13$

So

$y = 13$ $y=13$

$y = 13$ $y=13$ when $x = 5$ $x=5$ .

$y = 2 x + 3$ $y=2x+3$

$y = 2 (5) + 3$ $y=2(5)+3$

$y = 10 + 3$ $y=10+3$

$y = 13$ $y=13$

$13$ $13$

$y = 2 x + 3$ $y=2x+3$

Plugging in for $x = 5$ $x=5$ , we get

$y = 2 \cdot 5 + 3$ $y=2*5+3$

$y = 10 + 3$ $y=10+3$

$y = 13$ $y=13$
