Tricky question 11 to 12 maths, paper 3, question 31
If (L + M - N) = 68 and M = 31, WHAT IS (L - N) / 2?
Method needed, answer is 18 1/2 or 18.5
Thanks

If (L+M-N) =68
M=31
so( L+31-N) =68
(L-N) = 31 less than 68
L-N = 68-31 = 37
37/2 = 18.5
M=31
so( L+31-N) =68
(L-N) = 31 less than 68
L-N = 68-31 = 37
37/2 = 18.5

If (L + M - N) = 68 and M = 31
So subtract 31 or M from each side of the equation gives
(L - N) = 37
so (L - N) / 2 = 37 /2
= 18 1/2 or 18.5
