Question

X + 17 =52
5 + 3x = 20
2x - 200 - 42
3x - 10+ 5x = 70
10x - 30 +3x= 165
6x+21+ 2x=7x
3+2 (6-3)=7 AYUDAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA ​

Answer 1

Respuesta:

X + 17 =52

x = 52 -17

x = 35

5 + 3x = 20

3x = 20 - 5

3x = 15

x = 15/3

x = 5

2x - 200 = - 42

2x -200 = -42

2x = -42 + 200

2x = 158

x = 158/2

x = 79

3x - 10+ 5x = 70

3x +5x = 70 +10

8x = 80

x = 80/8

x = 10

10x - 30 +3x= 165

10x +3x = 165 +30

13x = 195

x = 195/13

x = 15

6x+21+ 2x=7x

6x +2x -7x = -21

x = -21

3+2 (6-3)=7

3 + 2(3) = 7

3 +6 -7 =0

2

ese no se x que esta ahi?
