x-2=(104-x)+2 6x-59=10x-75 (x+10)+(x-15)=280-x

问题描述:

x-2=(104-x)+2 6x-59=10x-75 (x+10)+(x-15)=280-x
4(x-62)=x-38 60x-40=(60+20)*(x-5) 32x+32*0.5-25x+64x=24x+496-49x
x+15=3*(109-x ) 5(3x-1.4)=2(6x-0.5) 3(x+0.9)=5(x-1.7)
13x-4(2x+5)=17(x-2)-4(2x-1) (13x+8)/3=5x-1
x-60=2[(3561-x)+100]+1 (x+9)+12=2[(x-9)-12]
