Question

6) If0.5(2x - 8) = 0.5x - 1, x=
(A) 2
(B) 3
(C) 6
(D) 0.2​

Answer 1

The correct option is c) 6

Answer 2

Answer:

x=6

Step-by-step explanation:

10x -40 by 10 = 5X-1 by 10

10 (x-4) by 10 = 5x-10 by 10

cross multiplication

100 (10x-40) = 50x-100

then we do this

10x40=50x-100 by 100

then,

10x-40 = 50 (x-2) by 100

then (X-2) by 2

then 10x-40=10 (x-4)

x-2 by 2 = X-4

x-2=2(x-4)

X-2 =2X-8

X-2X=-8+2

-X = -6

x=6
