Question

Calcule o valor de X nas equações

A) 8x+6-3x-2= -5X + 14

B)2X-10+5X = -X +14

C)7X+6-X-12= -14X+14

Answer 1

A) 8x +6 -3x -2 = -5X + 14
    8x -3x +5x = +14 -6 +2
    13x -3x = 16 - 6
    10x = 10
        x = 10 / 10
        x = 1


B) 2X -10 +5X = -X +14
     2x +5x +x = +14 +10
     8x = 24
       x = 24/8
       x = 3


C) 7X +6 -X -12 = -14X +14
     7x -x +14x = +14 -6 +12
     21x -x = +26 -6
     20 x = +20
          x = 20 / 20
          x = 1

vlw?

Answer 2

A) 8x+6-3x-2=-5x+14
    8x-3x+5x=14-6+2
    10x=10
        x=10/10   x=1


B)2x-10+5x=-x+14
   2x+5x+x=14+10
   8x=24
     x=24/8   x=3


C)7x+6-x-12=-14x+14
    7x-x+14x=14-6+12
    20x=20
        x=20/20     x=1
