Elena began to solve the equation below. When she got to the last line she stopped and said the equation is true for all values of x. How could Elena
tell?
12.1 + 6(4x + 3)
= 2(6x + 4) - 2
3
12x + 6(4x + 3) = 3(2(6x + 4) – 2)
12. + 6(4x + 3) = 6(6x + 4) - 6
12x + 24x + 18 = 36x + 24 - 6

what does x eaqual

step-by-step explanation:

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 %
