The number . . . . . N
The difference of the number and 9 . . . N-9
Seven times that difference . . . . . . . 7(N-9)
You said that 7(N-9) = 2 .
Divide each side by 7 : N - 9 = 2/7
Add 9 to each side: N = 9 and 2/7
It does not matter which he does first. Either way, zero pairs will be created on both sides, which will isolate the variable to determine x<span>. Adding the </span>x<span>-tiles and then the unit tile, or visa versa, will give the same solution.</span>
