Question

Resolva as equações: 1)-25+11X=30. 2)4X-11=-5X+25. 3)9X-6X+4X=35

Answer 1

Oi...

1) - 25 + 11x = 30

     11x = 30 + 25

      11x = 55

          x = 55/11

          x = 5

2) 4x - 11 = - 5x + 25

     4x + 5x = 25 + 11

       9x = 36

        x = 36/9

        x =  4

3) 9x - 6x + 4x = 35

     7x = 35

       x = 35/7

       x = 5

Bons estudos.

Answer 2

1)-25+11x=30
+11x=30+25
+11x=55
x=55 :11
x= 5

2) 4x-11=-5x+25
4x+5x= 25+11
9x=36
x=36:9
x=4

3)9x-6x+4x=35
3x+4x=35
7x=35
x=35:7
x=5

espero ter ajudado!!
