What is the solution of the system? use the elimination method.-4x - 2y = -122x + 4y = -12enter your answers in the boxes

(x, y) = (6, -6)

Divide the first equation by 2 to get equal and opposite coefficients for x.

... -2x -y = -6

Add this to the second equation to eliminate x.

... (2x +4y) +(-2x -y) = (-12) +(-6)

... 3y = -18 . . . . . . . . simplify

... y = -6 . . . . . . . . . . divide by 3

Substitute this vaue into any of the equations to find x. We choose to use the reduced first equation above.

... -2x -(-6) = -6

... -2x = -12 . . . . subtract 6

... x = 6 . . . . . . . divide by -2

The solution to the system is (x, y) = (6, -6).

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
