Giải lần lượt ra nha
TL:
435 x 85 + 435 x 45 - 435 x 31 + 435
= 435 x 85 + 435 x 45 - 435 x 31 + 435 x 1
= 435 x (85 + 45 - 31 + 1)
= 435 x 100
= 43500

tìm x biết :

xin mn giúp t đang gấp
315+[125-x]=435
125-x=435-315
125-x=120
x=125-120
x=5
\(315+\left(125-x\right)=435\)
\(125-x=435-315\)
\(125-x=120\)
\(x=125-120\)
\(x=5\)
315 + [ 125-x ] = 435
125-x = 435 - 315
125-x = 120
x = 125-120
x = 5
