Question

Resuelve las siguientes ecuaciones

5x+2=2x+8
-10x+8=-12
-4x+9=3x+5

Answer 1

1.

5x + 2 = 2x + 8

5x - 2x = 8 - 2

3x = 6

x = 6/3 = 2

2.

-10x + 8 = -12

-10x = -12 - 8

-10x = -20

x = -20/-10 = 2

3.

-4x + 9 = 3x + 5

-4x - 3x = 5 - 9

-7x = -4

x = -4/-7 = 4/7

Answer 2

5x+2=2x+8

5x-2x=8-2

3x=6

x=6/3

x=2

-10x+8=-12

8+12=10x

20/10=x

x=2

-4x+9=3x+5

9-5=3x+4x

4=7x

X=4/7
