Find the solution to the equations.

3x - y = -4

x + y = 0

( - 1, 1 )

Step-by-step explanation:

Given the 2 equations

3x - y = - 4 → (1)

x + y = 0 → (2)

Subtract y from both sides in (2)

x = - y → (3)

Substitute x = - y into (1)

- 3y - y = - 4, that is

- 4y = - 4 ( divide both sides by - 4 )

y = 1

Substitute y = 1 into (3)

x = - 1

Solution is (- 1, 1 )

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
