Answer:
x=3, y=-1. (3, -1).
Step-by-step explanation:
7x-5y=26
2x+4y=2
--------------
simplify 2x+4y=2 into x+2y=1
-------------
7x-5y=26
x+2y=1
-----------------
x=1-2y
7(1-2y)-5y=26
7-14y-5y=26
7-19y=26
19y=7-26
19y=-19
y=-19/19
y=-1
x+2(-1)=1
x-2=1
x=1+2
x=3
Solution
To find out which expressions represent the difference of exactly
two expressions
a) 6(x+7) - 2
This can be simplified as
6x + 42 - 2
6x + 40
Clearly this does not represent difference of the two
expressions .
b) -2j
Clearly this represents a single expression , this does not represent
a difference of 2 expression .
c) 4f - 2g
Here we have 2 different expressions 4f and 2g
Difference of these 2 expressions are 4f - 2g
Hence , this option represent difference of exactly two
expression
d) 3xyz - 10
3xtz - 10 represnts a single expression
Here we have a single expression
Therefore it does not represent difference of exactly 2
expression .

Answer:</h3>
B) (x + 7)^2 = 20
<h3>
Step-by-step explanation:</h3>
You can subtract 34 from the original equation to get
... x^2 +14x = -29
Now, you can add the square of half the x-coefficient, and you will have ...
... x^2 +14x +49 = -29 +49
... (x +7)^2 = 20 . . . . . . matches selection B

The question asks for the form (x -p)^2 = q, but that does not mean that p must be positive. Here, p=-7 and q=20.
