各位学霸们，怎么解答这道方程？
\u5b66\u9738\u4eec\uff0c\u6c42\u8fd9\u9053\u9898\u65b9\u7a0b\u89e3\u7b54\u600e\u4e48\u505a\uff1f\uff1f\uff1f\u6025\u5440\uff01\u8bbex\u4e2a\u6708\u540e\u4e59\u662f\u7532\u76842\u500d
\u6b64\u65f6\u7532\u670950+5x
\u4e59\u670988+12x
\u6709\u65b9\u7a0b\uff1a2(50+5x)=88+12x
100+10x=88+12x
2x=12
x=6
98x+98×44.1=133×1.4x
98x+4321.8=186.2x
186.2x-98x=4321.8
88.2x=4321.8
x=49
两边去括号得到98x+98*44.1=186.2x
移项得到88.2x=98*44.1
解得x=49
98(X+44.1）=133（X+40%X)
98X+4321.8=133*1.4X
4321.8=186.2X-98X
4321.8/88.2=X
X=49
