8x - 2(x + 1) = 2(3x - 1)
First, expand to remove parenthesis. / Your problem should look like:
Second, subtract 8x - 2x - 2 to get 6x - 2. / Your problem should look like:
Third, both sides are equal, so there are infinite solutions. The equation is always true.

Answer:
Dimensions of:
Rectangle A are 6 cm by 4 cm.
Rectangles B are 6 cm by 2 cm.
Step-by-step explanation:
It is given that:
The area of square is 36 cm^2.
Hence, the side of the square is given as:
Hence, the side of square is 6 cm.
Now, as the area of two rectangles A and B are in the ratio:
2:1
This means that, the area of rectangle A is 24 cm^2.
and area of rectangle B is 12 cm^2.
( Since, 36/(2+1)=36/3=12
Area of rectangle A=2×12=24 cm^2.
Area of rectangle B=1×12=12 cm^2. )
Hence, the dimensions of A are:
6 cm by 4 cm.
and the dimensions of rectangle B are:
6 cm by 2 cm.
