Step-by-step explanation:
So you add one over the other
3x-2y=7
-3x+5y=5
=
3y=12
Then you divide 3 from both sides
(3y)/3=12/3
y=4
Then you substitute the y=4 in to the equation of your choice
3x-2(4)=7
3x-8=7
3x-8=7
+8 +8
3x=15
x=5
4116 first answer 7 times 8 subtract 35.Second multiply by 14.Lastly solve 7 times 2 and multiply it by what you got multiplying 14.
The remainder theorem says that if

is a factor of a polynomial

, then the remainder upon dividing

is 0 so that there exists a lower degree polynomial

as the quotient:

Using the fact that

is a factor, you can find a quadratic

which is easy to factorize further.
Synthetic division yields

which can be factored further as

So,

The roots are then

.
Answer
a first one is 52 (90-38=52)
Second one is 32 (180-148=32
I can’t see the third or 4th one
