The answer is going to be x=28
Here is how I did it:
You first need to subtract it first
6x/7+15-8=31
6x/7+7=31
you have to find the common denominator
6x/7+7=31
6x/7+7*7/7=31
Multiply all the terms by the same value to eliminate fraction denominators
7(6x+49)/7=7*31
6x+49=7*31
Multiply the numbers
6x+49=7*31
6x+49=217
Subtract 49 from both sides
6x+49=217
-49 -49
Now theres 6x=168
Divide both sides
6x=168
—- —-
6 6
Simplify
x=28 is your answer
One way to solve this is to look at the size of the poster, and then subtract the size of the picture so you have the area that needs to be painted left.
Area of square poster - 3x × 3x = 9x^2
Area of painting - 2x × 2x = 4x^2
9x^2 - 4x^2 = 5x^2
The area is 5x^2
