Question

1/2 a number is equal to the sum of three-fourths of the number and -2.Find the number.

Answer 1

1/2 a number = x/2

the sum of three-fourths of the number and -2: 3/4 + -2 = -5/4

We know that they're equal, so:

x/2 = -5/4

Multiply both sides by 2 to isolate the x and find the number:

x = -5/2

Therefore, the number is -5/2.
