x + 4 = 15
- 4 -4
x = 11
You would subtract 4 because you need to isolate the x to get the value of x. You would subtract it to both sides because whatever you do on one side, you have to do it to the other side.

Answer:
44.125 inches
Step-by-step explanation:
Given that:
Length of picture = 32 1/2 inches
Length of wall = 120 3/4 inches
Hence, to center picture horizontally ;
Distance from the edge of the wall in which the picture should be placed :
(Length of wall - length of picture) / 2
(120 3/4 - 32 1/2) / 2
(483/4 - 65/2) / 2
Take the L. C. M of 4 and 2 = 4
((483 - 130) / 4) ÷ 2
(353 / 4) ÷ 2
(353 / 4) * (1 / 2)
= 353 / 8
= 44 1/8
= 44 1/8
= 44.125 inches
