Question

Resuelve las siguientes ecuaciones

Answer 1

1) X-10x+15=3(x-1)+4

x-10x+ 15=3x-3+4

-9x+15=3x-3+4

-9x+14=3x+1

-9x-3x+ 15=1

-9x-3=1 -15

-12x=1-15

-12x=-14

x=7

2) 2(x-5) +4=5x-2

2x-10+4=5x-2

2x-6=5x-2

2x -5x-6=-2

2x-5x=-2+6

- 3 x=-2+6

-3=4

x=- 4

3

x=-1 1, x=-1,3

3) 3- x +2 =15x-10

5

15-(x+2)=75x-50

15-x-2=75x-50

13-x=75x-50

13- x-75 x =-50

-x-75 x=-50-13

-76x=-50-13

-76x =- 63

x=63

76
