Please help me fill in the blanks. I know that the answer is 5 but no matter what i put in the blanks the system is rejecting my answers. Help

On paper, this is how I would expect students to do this
x/9 = 1/7 = 26/63
multiply each side by 63, the LCD
63(x/9)  63(1/7) = 63(26/63)
7x  9 = 26
7x = 35
x = 5
