b. x X 35 + x X 64 + x = 25
tính giúp mk ạ
cảm ơn
a) 543 x 125 - 543 x 24 - 543
= 543 x 125 - 543 x 24 - 543 x 1
= 543 x (125 + 24 + 1)
= 543 x 150
= 81450
b) X x 35 + X x 64 + X= 25
X x 35 + X x 64 + X x 1= 25
X x (35 + 64 + 1) = 25
X x 100= 25
X = 25 :100
X = 0,25 (25/100)
a)
\(543.125-543.24-543\)
\(=543.125-543.24-543.1\)

\(x .35+x.64+x=25\)
\(x.(35+64+1)=25\)
\(x.100 =25\)
\(x = 25:100\)
\(x = {1\over4}\)
