The height of a picture that will fit in the remaining height of the frame
will be 13.5 inches.
Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
To form an equation we need to know some constraints such that they can be solved and find out answers.
In other words, an equation is a set of variables that are constrained through a situation or case.
Given that the height of Liliana's picture = 18 inches
Frame and blue matting cover = 4.5 inches.
Let the remaining height is p then
p + 4.5 = 18
p = 18 - 4.5 = 13.5 hence 13.5 inches of picture can fit inside frame.
