Question

find the value of x

8-2x=1 and 1/5

how do you solve it, can you explain and then give me examples to try on my own thnx.

Answer 1

8-2x=1 and 1/5

-2x = -8 + 1 1/5

-2x = - 6 4/5

x = (-6 4/5) / -2

x = -3 2/5

Answer 2

i got 5 3/5 what did i do wrong?

Answer 3

check

8 - 2 x = 6/5

2 x = 40/5 - 6/5

2 x = 34/5

x = 17/5

x = 3 2/5

Answer 4

2 x = 40/5 - 6/5

why did you get 40/5

do you multiple 8x5 if so how come you didn't multiply 6x5

Answer 5

because I wanted a common denominator of 5

(8/1)(5/5) = 40/5

I already had 6/5 to subtract from that 40/5

and leave 34/5

Answer 6

I think our fellow use to simplify the arithmetics coz 40/5=8 so nothing was changed.then lets solve it correctly
8-2x =1 1/5 to get 6/5 u take denominator times the whole number plus the numerator(5*1)+1 the answer will be written over the as the new numerator dat 6/5
2x=40/5 - 6/5
2x=34/5
x=34/10
x=3 and 4/10 or simplified to 3 and 2/5.
