When solving the equation, which is the best first step to begin to simplify the equation? -2(X+ 3) = - 10
(-2}{2}{x+ 3) = - 10(-2)
- (-2)(x + 3) = -
- 10
- 10
2
(x+3) -
- (243) -10

-2(X+ 3) = - 10

Is the first step

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 %
