Question

ayuda 9(x + 2 =9 6(x+5)=18 4(6-x)=20. 4(3x+ 7)+5=33. 9+2(x+2)=19

Answer 1

Explicación paso a paso:

. 9(x+2)=9

9x+18=9

9x=9-18

9x=-9

x=-9/9

x=-1

.6(x+5)=18

6x+30=18

6x=18-30

6x=-12

x=-12/6

x=-2

.4(6-x)=20

24-4x=20

-4x=20-24

-4x=-4

x=-4/-4

x=1

.4(3x+7)+5=33

12x+28+5=33

12x+33= 33

12x=0

x=0/12

x=0

.9+2(x+2)=19

9+2x+4 =19

13+2x = 19

2x= 19-13

2x= 6

x= 6/2

x= 3

Espero haberte ayudado
