paul painted a triptych which measured 63 inches across. Each of the triptych's three panels is of equal width. How wide is each panel

Answer 1

If it is 63 in across, and each part is equal, the equation so solve this is:  63=3x
So, you take 63=3x and divide each side by 3
63/3=3x/3
Then simplify
21=x 
This means each panel is 21 inches wide.
