Mathematics

The two given equations are:
<span>-14=-20y-7x  and 10y+4=2x

In order to find x and y, we can do it by substitution or by elimination.

By Elimination.
</span><span>Multiply 10y+4=2x by 2
= 20y + 8 = 4x

Then add it to the second equation
</span>-20y - 7x = -14
20y - 4x = -8
---------------------
-11x = -22
x = 2

Then get y,
10y+4=2x 
10y = 2x - 4
10y = 2(2) - 4
y = 0.

So the answer is x = 2, y = 0

the question:

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. At the farmers market, Nathaniel buys two dozen oranges at $3.50 per dozen, four kilograms of apples at $3.25 per kilogram, two kilograms of carrots at $1.90 per kilogram, and one kilogram of potatoes for $1.20. He received a 5% discount off his total bill. How much money did Nathaniel spend on fruits and vegetables at the farmers market? Nathaniel spent $______ at the farmers market.

nathaniel got 2 dozen so 7$ for the oranges

4 kg  so 13$ for apples

2 kg so 3.8$ for carrots

1 kg so 1.2$ for potatoes

LETS ADD IT TOGETHER

25$ TOTAL

DISCOUNT=5%

5% OF 25 IS 1.25

SO 25-1.25=23.75

SO NATHANIEL SPENT 23.75$ IN ALL

HOPE I HELPED
