$= 44$ $=color(blue)(44$

Explanation:

$2 y + 9 x - 7$ $2y+9x-7$ is the expression provided to us.

The values for the variables are $y = 3 and x = 5$ $y=3 and x=5$

We substitute the values of the variables provided into the expression:

$2 y + 9 x - 7 = 2 \cdot 3 + 9 \cdot 5 - 7$ $2y+9x-7 =2*3+9*5-7$

$= 6 + 45 - 7$ $=6+45-7$

$= 44$ $=color(blue)(44$
