They are equal. 7 squared is 7 x 7, which equals 49. 6 x 7 = 42, plus another 7 = 49.
it equals 3.
x = 8
X=5, x+6, 5+6=11
6 * 5 = 30
6 x 7 is equal to 2 x 3 x 7. If you find the solution to 3 x 7, you can multiply it by 2 to get 6 x 7.
Strewth - 42 (and that was without a calculator)

ok im gonna show you how this works! :P x/7=6 x/7x7=6x7 x=42
x = 8
X=5, x+6, 5+6=11
6 * 5 = 30
x = -3
x2 = -80 x = (+/-)(-80).5 = (+/-)4isqrt(5)
5
If x=4... then 'y' MUST equal 3 !
