Solve the system of equations. \begin{aligned} &-5x+4y = 3 &x=2y-15 \end{aligned} −5x+4y=3 x=2y−15 x=x=x, equals y=y=

For the given system the value of x is 9 and value of y is 12.

Step-by-step explanation:

We are given the following system of equation in the question:

We solve the equation by substitution.

Substituting value, we get,

Thus, for the given system the value of x is 9 and value of y is 12.

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 %
