What is the solution of the system of equations X plus 3Y equals seven, 3X plus 2Y equals 083, to be -2, 3C2, negative3D -3, 28 -2 -3

B

Step-by-step explanation:

x + 3y = 7 → (1)

3x + 2y = 0 → (2)

Multiplying (1) by - 3 and adding to (2) will eliminate x

- 3x - 9y = - 21 → (3)

Add (2) and (3) term by term to eliminate x

0 - 7y = - 21

- 7y = - 21 ( divide both sides by - 7 )

y = 3

Substitute y = 3 into either of the 2 equations and solve for x

Substituting into (1)

x + 3(3) = 7

x + 9 = 7 ( subtract 9 from both sides )

x = - 2

solution is (- 2, 3 ) → B

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

//blooming serenity//

beautiful in the morning

mysterious at night

wonderous nature souring

with all it's mystical might

the flower that blooms

to the fox that looms

nocturnal creatures

with various features

a blooming flower soon in sight

as a new little hatchling fears to take flight  

afraid to leave it's calming nest,

but dear little bird, mother knows best

as sure as there are stars in the sky,

life is not about who, where what, when or why-

it's the journey that follows

adventures we swallow

of   nature's deep wonders,

natural disasters and storm's thunders.

blooming serenity

life and nature, truly is heavenly.
