5(x-5)+35=??/ Đề sai
4(x+5)-35=-72
4(x+5)=-72+35
4(x+5)=-37
đề sai
5(x-5)+35=.
<=>(5+x)=35+5
<=>5+x=40
=>x=40-5=35
=>5(35-5)+3=158
b,4(x+5)-35=-72
<=>3x-30=-7
=>3x=23
=>x=23/3
4(x+5)-35=-72
=) 4(x+5)=-37
=) x+5= -37:4=\(\frac{-37}{4}\)
=) x=\(\frac{-55}{4}\)
=) 5(x-5)+35=5(\(\frac{-55}{4}\)-5)+35=\(\frac{-229}{4}\)
Đáp số : \(\frac{-229}{4}\)nha :)
mk nha :)
