34kurt

Answer:

The space on each side of the painting = 2 feet

Step-by-step explanation:

Attached this answer is a diagram to give you visuals on how the value of x is calculated

Given:

width of wall = 10 feet

width of painting = 6 feet

Since the painting is centred on a wall, there is meant to be an equal space on each side of the painting, from the diagram, the following eaquation can be gotten

x + 6 + x = 10

2x + 6 = 10

2x = 10 - 6

2x = 4

x = 4 ÷2

x = 2 feet

Therefore, the space on each side of the painting = 2 feet
