a) 2x-3=x+8
b) 6x+10-15=4x+7
c)4x+7x-20=30+x
d)30-5x+1=x+1
e)7x+10-2x-12=2x+3+2x
f)-5+4x-2+7x+4x+10+7+x
g)-4x-3+10-8x=6x+15-8
h)4+8x+1-15=7x-32-15+1

Answer 1

fácil bueno algo asi

2x-3=x+8

2x - x = 8 + 3

x = 11

) 6x+10-15=4x+7

6x - 4x - 5 = 7

2x = 7 + 5

x = 12/ 2

x = 6

4x+7x-20=30+x

11x - x = 30+ 20

10x = 50

x = 50/10

x= 5

)30-5x+1=x+1

31 - 1 = x + 5x

30/ 6 = x

5= x

7x+10-2x-12=2x+3+2x

5x - 2 = 3 + 4x

5x - 4x = 3 + 2

x= 5

)-5+4x-2+7x+4x+10+7+x

16x - 7 + 17

16x + 10

)-4x-3+10-8x=6x+15-8

-3+10 - 12x. = 6x + 7

+7 - 7 = 6x + 12 x

0 = 18x

18 = x

4+8x+1-15=7x-32-15+1

8x - 10 = 7x - 46

8x - 7x = - 46 + 10

x= - 36
