Question

Х+3=7. 9-Х=2. х-4=10

Answer 1

Відповідь:

Покрокове пояснення:

Х+3=7

Х=7-3

Х=4

9-Х=2

-Х=2--9

-Х=-7

Х=7

Х-4=10

Х=10+4

Х=14

Answer 2

Пошаговое объяснение:

1) x + 3 = 7

  x = 7 - 3

  x = 4

2) 9 - x = 2

  x = 9 - 2

  x = 7

3) x - 4 = 10

  x = 10 + 4

  x = 14

Answer 3

To solve for the variable "x" in each equation, we need to isolate it on one side of the equation.

1. Х+3=7

Subtract 3 from both sides to isolate x:

Х+3-3 = 7-3

x = 4

Therefore, x = 4 is the solution to this equation.

2. 9-Х=2

Add X to both sides to isolate X:

9 - X + X = 2 + X

9 = X + 2

Subtract 2 from both sides to isolate X:

9 - 2 = X

7 = X

Therefore, x = 7 is the solution to this equation.

3. х-4=10

Add 4 to both sides to isolate X:

х - 4 + 4 = 10 + 4

х = 14

Therefore, x = 14 is the solution to this equation.
