x=2 đấy chính xác 100000000000000000000000000000000000000000000000% luôn
723 x X - 223 x X = 1000
X x ( 723 - 223 ) = 500
X x 500= 1000
X = 1000 : 500
X = 2
723 x X - 223 x X = 1000
X x (723 - 223) = 1000
X x 500 = 1000
X = 1000 : 500
X = 2
723*x-223*x=1000
x*(723-223)=1000
x*500=1000
x=1000:500
x=2
723 x X - 223 x X =1000
X x (723 - 223 ) = 1000
X x 500 =1000
X =1000 :500
X =2
Nếu thấy đúng thì k mình nha !
X x(723-223) =1000
Xx 500 = 1000
X =1000:500
X = 2
