To do this, we must allow this hidden number to be x.
2x + 4 = 8
Now we will solve by first subtracting 4 from each side:
2x = 4
Now we will divide each side by 2 to isolate the variable:
x = 2
Therefore, the mystery number is 2.
Answer:
1/3 ( 5y-2) = x
Step-by-step explanation:
5y = 3x+2
Subtract 2 from each side
5y -2 = 3x+2-2
5y-2 = 3x
Divide each side by 3
1/3 ( 5y-2) = 3x/3
1/3 ( 5y-2) = x
Consecutive integers are 1 apart
so they are n and n+1
the sum is adding them
the sum is 43
n+n+1=43
2n+1=43
minus 1 both sides
2n=42
divide both sides by 2
n=21
n+1=22
the integers are 21 and 22
Answer:
They are the same.
