Answer:
One example is the equation:
2x + 6 = 4x/2 + 12/2
To solve this, we need to transpose like terms to the same side.
2x - 4x/2 = 12/2 - 6
2x - 2x = 6 - 6
0 = 0
Since both sides are zero, it means that the equation has infinite number of solutions.

Answer:
the amount the stock changed over the day = $29
Step-by-step explanation:
The stock cost $122 at the start of the day . At the end of the day it cost $93. The amount the stock value changed can be calculated below.
The initial amount of the stock that days was $122 but at the end of the day it changes to $93. This means the stock cost decreases over the day.
Initial cost of stock at the day = $122
Final cost at the end of the day = $93
the amount the stock changes over the day = initial cost of stock at the day - final cost at the end of the day.
the amount the stock changes over the day = 122 - 93
the amount the stock changed over the day = $29
Generally, the stock decreased over the day.

Answer:
Area = 370 m²
Cost to paint = £105
Step-by-step explanation:
Area of the wall of a cinema hall = Area of a trapezoid (1)+ Area of a rectangle (2) + Area of a trapezoid (3)
Area of a trapezoid = 
where 
and 
are the parallel sides and h is the distance between these sides.
Area of trapezoid (1) = 
= 69 m²
Area of the rectangle (2) = Length × Width
= 12 × 15
= 180 m²
Area of the trapezoid (3) = 
= 121 m²
Now area of the wall = 69 + 180 + 121
= 370 m²
One tin covers the area = 25 m²
Number of tins required to paint the wall = 
= 
= 14.8
Therefore, number of tins to be purchased = 15
Cost to paint the complete wall = 15 × £7
= £105
