negative one times the sum of twice a number and 3 is equal to two times the difference of -4 times the number and 3. what is the number?

Answer 1

Written in Math, that would be

-1(2x + 3) = -4x - 3
-2x - 3 = -4x - 3
2x = 0
x = 0

check:

the sum of twice the number and 3 = 2(0) + 3 = 3
-1 times that = -3

the difference between -4 times the number and 3
= -4(0) - 3 = -3

yup, the answer is correct

Answer 2

written in math would be
-1(2x+3)=2(-4x-3)
-2x-3=-8x-6
-3=-6x-6
3=-6x
-0.5=x

Answer 3

misread the question, missed the "equal to two times"
