    Work: Find the solution of equation 30000(100+(a+5))%+2000×(5a/6)%*15(1+a%) = 21750+30000+2000*(5a/6)%*15 .
    Question type: Equation
    Solution:Original question:
     30000(100 + ( a + 5)) ×
1
100
+ 2000(5 a ÷ 6) ×
1
100
× 15(1 + a ) = 21750 + 30000 + 2000(5 a ÷ 6) ×
1
100
× 15
     Left side of the equation = 300(100 + ( a + 5)) + 300(5 a ÷ 6)(1 + a )
    The equation is transformed into :
     300(100 + ( a + 5)) + 300(5 a ÷ 6)(1 + a ) = 21750 + 30000 + 2000(5 a ÷ 6) ×
1
100
× 15
    Remove the bracket on the left of the equation:
     Left side of the equation = 300 × 100 + 300( a + 5) + 300(5 a ÷ 6)(1 + a )
                                             = 30000 + 300( a + 5) + 300(5 a ÷ 6)(1 + a )
                                             = 30000 + 300 a + 300 × 5 + 300(5 a ÷ 6)(1 + a )
                                             = 30000 + 300 a + 1500 + 300(5 a ÷ 6)(1 + a )
                                             = 31500 + 300 a + 300(5 a ÷ 6)(1 + a )
                                             = 31500 + 300 a + 300 × 5 a ÷ 6 × (1 + a )
                                             = 31500 + 300 a + 250 a (1 + a )
                                             = 31500 + 300 a + 250 a × 1 + 250 a a
                                             = 31500 + 300 a + 250 a + 250 a a
                                             = 31500 + 550 a + 250 a a
    The equation is transformed into :
     31500 + 550 a + 250 a a = 21750 + 30000 + 2000(5 a ÷ 6) ×
1
100
× 15
     Right side of the equation = 21750 + 30000 + 300(5 a ÷ 6)
                                               = 51750 + 300(5 a ÷ 6)
    The equation is transformed into :
     31500 + 550 a + 250 a a = 51750 + 300(5 a ÷ 6)
    Remove the bracket on the right of the equation:
     Right side of the equation = 51750 + 300 × 5 a ÷ 6
                                               = 51750 + 250 a
    The equation is transformed into :
     31500 + 550 a + 250 a a = 51750 + 250 a

    The solution of the equation:
        a1≈-168.166538 , keep 6 decimal places
        a2≈48.166538 , keep 6 decimal places
    
    There are 2 solution(s).
