2x + y = 1 . . . . . (1)
4x + 2y = -2 . . . .(2)
From (1), y = 1 - 2x . . . . . (3)
Putting (3) into (2) gives:
4x + 2(1 - 2x) = -2
4x + 2 - 4x = -2
2 = -2
Therefore, there is no x value as there is no solution for the set of equation.

Answer:
Yes it is valid
Step-by-step explanation:
A square is a geometric shape which is also known as a Quadrilateral. This means that it has 4 sides.
For a square, it's 4 sides are equal to one another or we can put it in other words as the length of the 4 sides of a square are congruent to one another.
From the above question, we are asked that:
"If a square has a side length of 3, it's area is 9. Is it valid or invalid?"
The above statement is valid. This is because, the formula for the Area of a Square is given as
L × L = L²
Where L = Side length = 3
Area = 3 × 3 = 3²
Area = 9
Therefore, the statement is valid.

Answer:
84
Step-by-step explanation:
The area of a parallelogram is base * height.
Base = 12
Height = 7
12 * 7 = 84
