Answer:
about $2269
Step-by-step explanation:
If we assume the aspect ratio of the two screens is the same, then the area is proportional to the square of the diagonal dimension.
__
The diagonal dimension of the larger HDTV is 65/32 ≈ 2.0313 times that of the smaller one. So, the price is expected to be ...
$550 × 2.0313² ≈ $2269.29
You expect the 65" HDTV to cost about $2269.
Solve for x (isolate/get x by itself)
Add 5 on both sides

Subtract 1/4x on both sides

Make the denominators the same of the fractions in order to combine them. Multiply 2 to the top and bottom of 1/4x

Multiply 8 on both sides

-16 = x
