b)x-6+9-10=20-30-1

c)x+8-6+10=3+10-11

d)x+2-9-10=3+1-9

e)x+6-4+18=20-6-10​

Answer 1

Explicación paso a paso:

a) x+10-6+8=20-3-1

x+12= 16

x= 16-12

x=4

b)x+10-6+8=20-3-1

x-7=-11

x= -11+7

×=-4

c)x+8-6+10=3+10-11

×+8-6=3-11

×+2=-8

x= -8-2

x= -10

d)x+2-9-10=3+1-9

x+2-10=3+1

x-8=4

x= 4+8

×=12

e)x+6-4+18=20-6-10

x+20=4

x=4-20

x=-16
