[ 1/1 Equation]
    Work: Find the solution of equation 90/x+90/(x+13.2) = 1 .
    Question type: Equation
    Solution:Original question:
     90 ÷ x + 90 ÷ ( x +
66
5
) = 1
     Multiply both sides of the equation by: x
     90 + 90 ÷ ( x +
66
5
) × x = 1 x
     Multiply both sides of the equation by:( x +
66
5
)
     90( x +
66
5
) + 90 x = 1 x ( x +
66
5
)
    Remove a bracket on the left of the equation:
     90 x + 90 ×
66
5
+ 90 x = 1 x ( x +
66
5
)
    Remove a bracket on the right of the equation::
     90 x + 90 ×
66
5
+ 90 x = 1 x x + 1 x ×
66
5
    The equation is reduced to :
     90 x + 1188 + 90 x = 1 x x +
66
5
x
    The equation is reduced to :
     180 x + 1188 = 1 x x +
66
5
x

    The solution of the equation:
        x1≈-6.841676 , keep 6 decimal places
        x2≈173.641676 , keep 6 decimal places
    
    There are 2 solution(s).
