Answer:
Uhm, this question is in world languages when it should be in mathematics, but ill answer it anyway.
Explanation:
1: Subtract the numbers.
x - 4 - 5 = 7
x - 9 = 7
2: Add 9 to both sides.
x - 9 = 7
x - 9 + 9 = 7 + 9
3: Add the numbers.
x - 9 + 9 = 7 + 9
x = 7 + 9
4: Add again.
x = 7 + 9
x = 16
Therefore, your answer is x = 16 :)
