So solving the equation X1 + X2 + X3 = 2, we get the number of solutions where X1 exceeds its bound. Following the similar way we can find out the number of solutions where X2 and X3 exceeds their bounds. Then we can deduct all of these invalid solutions from the ...
points of the absolute value equation x-51+Ix-71=2 are 5 and 7.The critical distance is then 7-5 =2,which equals the right hand side of the equation.This means that no matter what x we chose, Ix-51+Ix-7I will always equal 2,so the equation has infinitely many solutions.优质解答...
