Set up an equation and solve for unknown variable. “The difference of 2 and a number is equal to the sum of 5 and that same number”

x = 3/2 or 1.5

Step-by-step explanation:

Let the unknown number be x.

Translating the word problem into an algebraic expression, we have;

2 - x = 5 + x

Rearranging the equation, we have;

x + x = 5 - 2

2x = 3

x = 3/2

x = 1.5

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
