Let x be the number.
Then "two more than a number" is x + 2;
"1 less than 4 times the reciprocal of the number" is 4/x-1.
As the two expressions are equal, we have
x%2B2=4%2Fx-1
Solving for x, we have
x%5E2%2B2x=4-x multiply both sides by x
x%5E2%2B3x-4=0
%28x%2B4%29%28x-1%29=0
So
x=1 or x=-4
Therefore the number is 1 or -4.
