Question

resolva a equacao
5+6x=5x+2
calculos por vavor
segunda equacao x+2x-1-3=x
terceira equacao -3x+10=2x+8+1

Answer 1

5+6x=5x+2
6x -5x = 2 -5
x = -3


x+2x-1-3=x
x +2x -x = 3 +1
2x = 4
  x = 4/2
  x = 2


-3x+10=2x+8+1
-3x -2x = 8 +1 -10
-5x = -1
   x = -1/-5
   x = 1/5

Answer 2

5+6x=5x+2

6x-5x=2-5
x=-3

x+2x-1-3=x
x+2x-x=1+3
2x=4
x=4/2
x=2

-3x+10=2x+8+1
-3x-2x=8+1-10
-5x=-1 x(-1)
5x=1
x=1/5
x=0,2
