Answer:
The most simple method for solving systems of equations is to transform one of the equations so it allows for the canceling out of a variable. In this case, we can multiply \displaystyle 3x + y = 8 by to get . Then, we can add \displaystyle 2x + 4y = 12 to this equation to yield , so .

The answer is D.
The first one says you add -4 each time in the sequence.
The second says you add -2 each time in the sequence.
The third says you multiply by -2 each time in the sequence.
The fourth says you multiply by -4 each time in the sequence.
-2*-4=8
8*-4=-32
The answer is simple to work out you do 3/8 + 1/3
but the denominators are different so you find the lowest common multiple in this case 24 .
the frection is now 9/24 + 8/24 this is 17/24
I changed the fraction by doing this 24(common multiple) divided by 8 (denominator) that's how I got it if you don't understand just ask me
Answer:
3. 10 - 5 is 5. so that is the difference. difference means subtraction.
4. 108 - 30 = 78. so she can move 78 degrees miore after therapy because 108 minues 30 is 78
5. 99 because 180 - 81 = 99. there is always 180 degrees in a line angle.
6. 130 degrees. 25 + 25 = 50 so 180 minus 50 equals 130
