Question

X-7 =69 X+5=44. X -7=16

Answer 1

Покрокове пояснення:

1) х - 7 = 69

  х=69+7

  х= 76

2) х+5=44

   х=44-5

   х=39

3) х-7=16

   х= 16+7

   х=23

Answer 2

Ответ: 76; 39; 23.

Пошаговое объяснение:

х - 7 = 69

х = 69 + 7

х = 76

Проверка:

76 - 7 = 69

х + 5 = 44

х = 44 - 5

х = 39

Проверка:

39 + 5 = 44

х - 7 = 16

х = 16 + 7

х = 23

Проверка:

23 - 7 = 16  

Answer 3

Let's solve the equations one by one:

1. X - 7 = 69

To solve for X, we need to isolate X on one side of the equation. We can do this by adding 7 to both sides:

X - 7 + 7 = 69 + 7 X = 76

Therefore, the solution for the first equation is X = 76.

2. X + 5 = 44

Again, to isolate X, we'll subtract 5 from both sides:

X + 5 - 5 = 44 - 5 X = 39

Thus, the solution for the second equation is X = 39.

3. X - 7 = 16

In a similar manner, we'll add 7 to both sides:

X - 7 + 7 = 16 + 7 X = 23

Hence, the solution for the third equation is X = 23.

To summarize: X = 76 (from the first equation) X = 39 (from the second equation) X = 23 (from the third equation)
