Question

resolver las siguientes ecuaciones con comprobacion 3X-2=6x, 2/5X+3=5/2x-20, 2X+3(X-2)+4x=5X-7(2x-3)

Answer 1

•) 3X - 2 = 6X

3X - 6X = 2

-3X = 2

X = -2/3

Comprobando

3(-2/3) - 2 = 6(-2/3)

-2 - 2 = 2 (-2)

-4 = -4

•) 2X/5 + 3 = 5X/2 - 20

20 + 3 = 2X/5 + 5X/2

23 = (4X + 25X)/10

230 = 29X

230/29 = X

Comprobando

(2/5)(230/29) + 3 = (5/2)(230/29) - 20 》230/5 = 46

92/29 + 3 = 530/29 - 20

23 = (575 - 92)/29

23 = (667)/29

23 = 23

•) 2X + 3(X - 2) + 4X = 5X - 7(2X - 3)

2X + 3X - 6 + 4X = 5X - 14X + 21

2X + 3X + 4X + 14X - 5X = 21 + 6

18X = 27

2X = 3

X = 3/2

Comprobando

2(3/2) + 3 (3/2 - 2) + 4(3/2) = 5(3/2) - 7(2×3/2 - 3)

3 - 3/2 + 6 = 15/2 - 7(3 - 3)

9 = 15/2 + 3/2 - 7(0)

9 = 18/2 = 9
