Question

数学解方程，要写具体过程

35%X+(X+3)*36%+(11-2x-3)*40%=11*38.5

Answer 1

35%X+(X+3)*36%+(11-2x-3)*40%=11*38.5
35%X+36%X+3*36%+11*40%-2x*40%-3*40%=11*38.5
0.35X+0.36X+1.08+4.4-0.8X-1.2=423.5
-0.09X=423.5-1.08-4.4+1.2=419.22
X=4658

Answer 2

0.35x+0.36(X+3)+0.4(8-2X)=423.5
化简。。得
-0.09x=419.22
x=4658

Answer 3

0.35x+0.36x+1.08+4.4-0.8x-1.2=11*38.5
-0.09x+4.28=423.5
-0.09x=419.22
x=-4658
