X+y=3
2x-y=3
using elimination method

x = 2 , y=1

Step-by-step explanation:

to solve the equation using elimination method we say

let

x+y=3 equation 1

2x-y=3 equation 2

add all the equation together inorder to get rid of y

we have

  x + y = 3

+ 2x -y = 3

3x = 6

divide both sides by 3

3x/3 = 6/3

x = 2

substitute for x = 2 in equation 1 to get the value of y

x+y=3 equation 1

2 + y = 3

y = 3 -1

y =2

therefore the value of x and y is 2 & 1 respectively

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.
