Answer:
x ∈ (- 9/2; 1/2), it can also be written as -9/2 <x< 1/2
Step-by-step explanation:
We have absolute value, so we will have2 inequalities.
2x + 4 < 5 and -(2x +4)< 5
2x < 1 -2x - 4 < 5
x < 1/2 -2x < 9
or x > -9/2
(-∞; 1/2) or (- 9/2; ∞)
(-∞; 1/2) ∩ (- 9/2; ∞) = (- 9/2; 1/2)
The answer is x ∈ (- 9/2; 1/2), it can also be written as -9/2 <x< 1/2.
Answer:1=1
Step-by-step explanation:Let your no.= x
double the number=2x
add 4 = 2x+4
subtract same number=2x+4-x
subtract 3=2x+4-x-3
I get my number plus 1=x+1
so equation we get
2x+4-x-3=x+1
x+1=x+1
x=x
it means x is equal to all real number
So your number can be any real number
