Question

negative 1 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

1.5

Explanation:

Let the number be denoted as "a"

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

-2a - 3 = -8a + 6

-2a + 8a = 6 + 3

6a = 9

a = 9/6

a = 3/2 = 1.5
