Hello!
-2x + y = 1
-4x + y = -1
You can subtract these equations from each other to eliminate y
2x = 2
Divide both sides by 2
x = 1
Put this into one of the original equations
-2(1) + y = 1
Combine like terms
-2 + y = 1
Add 2 to both sides
y = 3
The answer is D) (1, 3)
Hope this helps!
Combine the like terms, then the final equation is the answer
Answer:
1 1/2.
Step-by-step explanation:
If 1/2 of a cup covers 1/3 add it twice you get 2/2 and you get 2/3 add it one more time and you get 1 1/2 or 3/3.
So when you have a -(-) then you make that a positive so that would mean - (+) so the two - - are positive and just one - is still negative, which would mean that the answer is -3. Because if the negative is greater that the positive then it is still a negative, in your mind you should make 13 positive minus 10 and then add the negative to make things easier if you want to.
11.11
<span>5/45 = x/100 (reduce fraction to lowest terms to make it easier to work with)
1/9 =x/100
.1111 = x/100
.1111x100 = x
11.11 = x
