Answer 1

QUESTION:

$5x + 4x = 9 + 9 + 9 + 9$

solve for x

ANSWER:

First of all we add the terms in LHS side and RHS side.

$9x = 36$

now in LHS side 9 is in multiplication with x so on other side of the equal it's operation will be changed it will be division

$x = \frac{36}{9}$

$x = 4$

FINALANSWER :

$\huge\red{x = 4}$

Answer 2

$\huge{\boxed{\mathscr\pink{♡}{\mathscr{Answer}}\pink{♡}}}$

➡5x+4x=9+9+9+9

We move all terms to the left:

5x+4x-(9+9+9+9)=0

We add all the numbers together, and all the variables

5x+4x-36=0

9x-36=0

9x=36

x=36/9

➡final ans

x=4
