Question

x+30=3x+20 , 4x-4=3x+6 ,p-9=-15 ,x+5=2x-80 ,-2m=36
ayúdenme con esas ecuaciones por favor .

Answer 1

Respuesta:

x+30=3x+20

x-3x=20-30

-2x=-10

rpta x=5

4x-4=3x+6

4x-3x=6+4

rpta x=10

p-9=-15

p=-15+9

rpta p=-6

x+5=2x-80

x-2x=-80-5

rpta x=85

-2m=36

rpta m=-18

Answer 2

Explicación paso a paso:

-> x+30=3x+20

x-3x=20-30

2x= -10

x= -10/-2= 5

-> 4x-4= 3x+6

4x-3x=6+4

x=10

-> p-9= -15

p= -15+9

p= -6

-> x+5=2x-80

x-2x= -80-5

x=85

-> -2m=36

m= 36/-2

m=18
