Make the coefficient of y the same in both equations:
To do this, multiply equation one by 2, and equation two by 5 (this will make the coefficient 10 in both).
14x + 10y = 38
-35x - 10y = -80
Eliminate the y variable by adding the equations from each other
(14x + 10y = 38)
+ (-35x - 10y = -80)
= -21x + 0y = -42
We now have -21x = -42. The y variable has been eliminated.
Solve for x
-21x = -42
Divide both sides by -21 to get x on its own.
x = 2
Substitute x into the equation to find y.
7*2+5y=19
14+5y=19
Subtract 14 from both sides.
5y=19-14
5y=5
Divide by 5 on both sides to get y on its own.
y=5/5
y=1
The answer is (2,1)

Answer:
7, 11, 13, 17, 19
All of these numbers only have 1 and themselves as factors, and every other number can be written as a product of two or more primes, making the remaining number composite:
Answer:
acres
Step-by-step explanation:
Divide 10 by 43:
10/43
In simplest form as a fraction, this is
So, each section would have acres
210/35% in the calculator it’s 135.50
