A projector displays a rectangular image on a wall. The height of the wall is x feet. The area (in square feet) of the
projection is represented by x2- 12x + 32. The width of the projection is (x - 4) feet.

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
