32x-5-43y+4=5(x+1)/5=y+232x-5-43y+4=5(x+1)/5=y+232x-5-43y+4=5(x+1)/5=y+2参考：2（x-1）-3（y+2）=4、x+1/2-2y+
32x-5-43y+4=5 (x+1)/5=y+2
32x-5-43y+4=5 (x+1)/5=y+2
32x-5-43y+4=5 (x+1)/5=y+2
参考：2（x-1）-3（y+2）=4、x+1/2-2y+5/3=1
如果是要求X和Y的值得话
2（x-1）-3（y+2）=4 把括号拆开得到 2X-2-3Y-6=4 移项得 2X-3Y=12①
x+1/2-2y+5/3=1 等式两边同时乘以6,得到6X+3-12Y+10=6 移项得 12Y-6X=7②
①×3+②：3Y=43 得到Y=43/3,将Y代入①可以得到X=55/2
