Answer: x = 6 .
_________________________________
Step-by-step explanation:
____________________________________________________
Given: 9x + 3 = 57 ; Solve for "x" ;
___________________________________
Subtract "3" from EACH side of the equation:
_________________________________________
9x + 3 − 3 = 57 − 3 ;
_________________________________________
to get:
_________________________________________
9x = 54 ;
__________________________________________
Now, divide EACH side of the question by "9" ; to isolate "x" on one side of the equation; and to solve for "x" ;
____________________________________________
9x / 9 = 54 / 9 ;
____________________________________________
x = 6 .

first you subtract 3 on both side
9x=57-3
9x=54

then you divide by 9 on both sides
you got
x=54/9

x=6
