Answer:
-9
Step-by-step explanation:
Step 1 : Put like terms together
x + 9 = 21 + 3x - 4 + 10
Subtract 3x on both sides
-2x + 9 = 21 - 4 + 10
Subtract 9 on both sides
-2x = 21 - 4 + 10 - 9
Simplify
-2x = 18
Step 2 : Divide
= 
x = -9
Fraction means a part of something
we see
18 times a fraction is bigger or smaller or equal to 18
18 times a fraction means take a part ouf of 18
in this case
18 times 4/5=72/5=14.4
14.4 is less than 18
when you take a fraction of something, it becomes smaller, like if you take a slice of pizza or a fraction of the pizza, it becomes smaller
