Ten less than a number is equal the same number divided by 2 what is the number

x-10=x/2

Simplify both sides of the equation.

x−10 = x /2

x+-10 = 1/2 x

x-10 = 1/2 x

Subtract 1/2 x from both sides.

x-10-1/2 x = 1/2 x - 1/2 x

1/2 x-10 = 0

Add 10 to both sides.

1/2 x-10+10 = 0+10

1/2 x = 10

Multiply both sides by 2.

2*(1/2 x) = (2)*(10)

Your answer should be: x = 20

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
