I have a quiz due in 12 hours, i have to show my work so please tell me how to do it and what to write down, if youre able to help, thank you :) (ill type them here)
Solve for x.
A. 7x-3=4x+3
B. 6(-2-z)=-5(2x+4)​

A.

7x-3=4x+3

7x-4x=3+3

3x=6

x=6/3

x=2

B.

6(-2-z)=-5(2x+4)

-12-6z=-10x - 20

10x=12+6z-20

10x= -8+6z

x=(-8+6z)/10

Since the 2nd one is equation in 2 variables there isn't a specific answer to it I just simplified it and solved for x

Hope it helps

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 %
