[ 1/1 Equation]
    Work: Find the solution of equation 120+(x-120)x2/5 = 1/2x .
    Question type: Equation
    Solution:Original question:
     120 + ( x 120) x × 2 ÷ 5 = 1 ÷ 2 × x
     Left side of the equation = 120 + ( x 120) x ×
2
5
    The equation is transformed into :
     120 + ( x 120) x ×
2
5
= 1 ÷ 2 × x
    Remove the bracket on the left of the equation:
     Left side of the equation = 120 + x x ×
2
5
120 x ×
