Question

TÌM X :-5.(X+6)-20X=5-10.(X-1)

Answer 1

-5x+(-5.6)-20x=5-(10x-10.1)

(-5x-20x)-30=5-10x+10

-25x-30=15-10x

-25x+10x=30+15

-15x=45

x=45:(-15)

x=-3

Answer 2

-5.(X + 6) - 20X = 5 - 10.(X - 1)

=> -5x - 30 - 20x = 5 - 10x + 10

=> -5x - 20x + 10x = 5 + 10 + 30

=> -15x = 45

=> x = -3
