Calculate gross profit when there's 20 cows(milk) 50,000 gallons and market price is $2.50 per gallon, 30 sheep (wool) 900 pounds market price $3.50 per pound, 40 chickens (eggs) 1023 dozen market place $2.96 per dozen, 100 acres corn 13,000 bushels market price at $3.48 per bushel, 100 acres wheat 3,700 bushels market price at $9.23 per bushel, 100 acres soybeans 6,600 bushels market price at $4.00 per bushel, 5 acres of peaches 2,700 bushels market price at $28.00 per bushel.

Ok here we go ..there are plenty of ways to solve such math problems but we will go for the smartest and easiest ..5x+2y=7  -2x+6y=9we rearrange them into the following ..by multiplying the 1st equation by 2 it becomes 10x + 4y = 14we rearrange it and so it becomes 10x = 14 - 4yas for the second equation we multiply it by 5 and rearrange it so it becomes as to the following ..-10x + 30y = 45rearranging so 10x = 30y -45now 10x equals both 14 - 4y and 30y -45so   14 - 4y = 30y -4531 = 26yy= 31/26 = 1.19 or around 1.2so by now we can calculate x easily as  -2x+6y=9so 2x = 6y -9 = 6 * 31/26 - 9 = -1.84  then x = - 0.92 or around -0.9best luck!
