Question

61-х=24 х-31=69 84+х=99

Answer 1

Ответ:

1) 61 - х = 24

х = 61 - 24

х = 37

                         

61 - 37 = 24

24 = 24

2) х - 31 = 69

х = 69 + 31

х = 100

                           

100 - 31 = 69

69 = 69

3) 84 + х = 99

х = 99 - 84

х = 15

                             

84 + 15 = 99

99 = 99

Answer 2

1)x=61-24
x=37
2)x=69+31
x=100
3)x=99-84
x=15

Answer 3

To solve these equations for the variable "x," you need to isolate "x" on one side of the equation. Here are the solutions for each equation:

1. 61 - x = 24

   To isolate x, subtract 61 from both sides:

   -x = 24 - 61

   -x = -37

   Now, to get rid of the negative sign in front of x, multiply both sides by -1:

   x = 37

2. x - 31 = 69

   To isolate x, add 31 to both sides:

   x = 69 + 31

   x = 100

3. 84 + x = 99

   To isolate x, subtract 84 from both sides:

   x = 99 - 84

   x = 15

So, the solutions for the equations are:

1. x = 37
2. x = 100
3. x = 15
