Answer: the option A.
The elimination method consist is adding the two equations in a way that one variable be eliminated..
In order to do that you might have to manipulate on of the equations prior to add the two equations.
In this case, ff you multiply the second equation by - 1 you will get
- x - y = - 4
which you can add to the first equation
2x + y = 8 to eliminate the y.
Find a common multiple in between the denominators.
10 and 3 and 5 -> the least common multiple is 30.
Change all the denominators to 30 by multiplying the top and bottom by the same number.
9/10=27/30
1/3=10/30
1/5=6/30
Subtract!
27/39-10/30-6/30=11/30
The answer is 11/30
Hope this helps!
Answer:
D) infinitely many solutions
Step-by-step explanation:
6x + 1 = 2(3x - 2) + 5
Distribute
6x+1 = 6x -4+5
Combine like terms
6x+1 = 6x+1
Subtract 6x from each side
6x-6x+1 = 6x-6x+1
1=1
This is always true, so x has infinite solutions
