Hey there!
9 * 7 = x * 9
9 * 7 = 63
63 = x * 9
x * 9 = 63
9x = 63
Divide 9 to BOTH SIDES
9x/9 = 63/9
CANCEL out: 9/9 because that gives you 1
KEEP: 63/9 because it gives you the x-value
x = 63/9
63/9 = x
x = 7
9 * 7 = 7 * 9
The number that belongs in the blank (your answer) is: 7
Good luck on your assignment and enjoy your day!
