Question

I think of a number, double it, subtract 3,

the result is 7. Evaluate the number that I first thought of.

Answer 1

5

Explanation:

2x - 3 = 7

this equation can represent the senario because the number (x) is doubles (multiplyed by 2), subtracted by 3 then equal to 7

then you can just solve for x

2x=10

x=5
