解不等式组{3(x-1)+13>5x-2(5-x) {5-(2x+1)<3-6x
解不等式组{3(x-1)+13>5x-2(5-x) {5-(2x+1)<3-6x

解不等式组{3(x-1)+13>5x-2(5-x) {5-(2x+1)<3-6x
3(x-1)+13>5x-2(5-x)
去括号得3x-3+13>5x-10+2x
移项得3x-2x-5x>-10+3-13
合并同类项得-4x>-20
系数化1得X

{3(x-1)+13>5x-2(5-x) {5-(2x+1)<3-6x 3X-3+13>5X-10+2x ,移项,4x<20,系数化为一,X<5 5-2X-1<3-6X 移项 4X<-1 系数化为一 X<-0.25
