Given expression is
-33/-10- (-45.3+ 35.2)
Problem says that it is simplified.
After simplification it gives:
-33/-10+?
Now we need to find the unknown value that goes in place of ?.
Notice that it is expression having only constants so we will get a unique answer not the smallest or largest value.
Now let's find the value of unknown that goes in place of ?
-33/-10- (-45.3+ 35.2)= -33/-10+?
we see that -33/-10 is on both sides so we can remove that
- (-45.3+ 35.2)= ?
Now let's simplify the left side by distributing the negative sign
+45.3 - 35.2= ?
10.1 = ?
Hence the unknown value is 10.1 that goes in place of ?.
19/21 would be your answer
Answer:
x=2
Step-by-step explanation:
5 ( x - 2) + 4 ( 3 + x) = 20
Distribute
5x -10 +12 +4x = 20
Combine like terms
9x +2 = 20
Subtract 2 from each side
9x+2-2 = 20-2
9x = 18
Divide each side by 9
9x/9 = 18/9
x = 2
