Answer:
The correct answer to the question is:
The difference between Shelly's and Terrence's total points.
Let
Eq1 : x - 2y = 12
Eq2 : 4x + 2y = 16
For substitution, we need to rearrange on of the equations so that we can substitute it in the other. Let's pick eq2 and rewrite it as 2y = 16 - 4x. We see that eq1 also has 2y in it, so we can plug this new version of eq2 in there.
3x - (16-4x) = 12
Now solve for x.
7x=28, so x=4
Plug that into either equation to solve for y. You get y=0.
So your answer is x=4, y=0
Um.. :/ you can do all 4 operations, I think adding or subtraction will be the easiest while division might be the hardest.
For division it looks sum like this.
(3x^2+5x+2)/(2x+1)
Multiplication:
(x+5)(x-3)
Addition:
<span>(2x
+ 5y) + (3x – 2y)</span>
Subraction:
<span>(x3 + 3x2 + 5x – 4) – (3x3 – 8x2 – 5x + 6) or simpler
Sorry for the wait I had to find your examples

Step-by-step explanation:
Answer:
1/4
Step-by-step explanation:
1/6 + 1/12
Multiply the numerator and denominator of the first fraction by 2.
2/12 + 1/12
Add both fractions, because they have a common denominator.
3/12
The fraction can be further simplified.
1/4
