Answer:
Unless you wrote the wrong expressions, non of your choice answers are correct!
Explanation:
Solve for x:
2 (x - 7) = 36
Divide both sides of (x - 7)×2 = 36 by 2:
(2 (x - 7))/2 = 36/2
2/2 = 1:
x - 7 = 36/2
The gcd of 36 and 2 is 2, so 36/2 = (2×18)/(2×1) = 2/2×18 = 18:
x - 7 = 18
Add 7 to both sides:
x + (7 - 7) = 7 + 18
7 - 7 = 0:
x = 18 + 7
18 + 7 = 25:
Answer: x = 25
