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?

-1*3n=2 * (-4*3n)

-1 (3+n) = 2 (-4*3n)

so lets take the left hand side of the equation the first part. it says - 1 times the sum of 2 times a number and 3. you are closer. just the left side first.

equals - 3+-n

i think it would be - 1 (2n+3) = for the left hand side. that gives - 1 times the entire sum of 2n (2 times a number) and 3. the and implies

-2n-3=-8n-6 + 2n + 2n - 3=-6n-6 + 6 + 6 3=-6n ... - 6 - 6 n=-0.5

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

-2x - 3 = - 8x - 6

-2x + 8x = - 6 + 3

6x = - 3

x = - 3/6

x = - 1/2 < = = ur number
