Question

ecuacion
2x-25 = 105
108 = 4x-16
2x+40 = x+98
36 = 2x-8
3x =x+20
60 = 2x-10

Answer 1

Resolvamos:
1) 2x-25 = 105
2x= 105+25
2x= 130
X=130/2
X=65.....

2) 108 = 4x-16
-4x=-16-108
-4x= -124
X= -124/-4
Cambiamos de signo:
X= 124/4
X=31

3) 2x+40 = x+98
2x-x=98-40
2x-x=58
1x=58
X=58/1
X=58

4) 36 = 2x-8
2X=-8-36
2X= -9
X= -9/2
X= -4. 5

5) 3x =x+20
3x-x=+20
-2x=+20
X= +20/-2
X=-10

6) 60 = 2x-10
-2x=-10-60
-2X= -70
Cambiamos de signo:
2X=70
X=70/2
X= 35.
Bueno. Espero te sirva :)

Answer 2

1) 2x-25 = 105
2x=105+25
2x=130
x=130/2
x=65

2) 108 = 4x-16
4x-16=108
4x=108+16
4x=124
x=124/4
x=31

3) 2x+40 = x+98
2x-x=98-40
x=58

4) 36 = 2x-8
2x-8=36
2x=36+8
2x=44
x=44/2
x=22

5) 3x = x+20
3x-x=20
2x=20
x=20/2
x=10

6) 60 = 2x-10
2x-10=60
2x=60+10
2x=70
x=70/2
x=35
