\(2x+5=60-\left(3x-25\right)\\ \Leftrightarrow2x+5=60-3x+25\\ \Leftrightarrow2x+3x=60+25-5\\ \Leftrightarrow5x=80\\ \Leftrightarrow x=16\)
2x + 5 = 60 - 3x + 25
2x + 5 = 85 - 3x
2x + 3x = 85 - 5
5x = 80
x = 80 : 5
x = 16
2x+5=60−(3x−25)
⇔2x+5=60−3x+25
⇔2x+3x=60+25−5
⇔5x=80
⇔x=16
@Mốc
2x + 5 = 60 - (3x - 25)
⇔ 2x + 5 = 60 - 3x + 25
⇔ 2x + 3x = - 5 + 60 + 25
⇔ 5x = 80
⇔ x = 16
#chuchoctot:)))
2x+5=60-(3x-25)
⇔2x+5=60-3x+25
⇔2x+3x=60+25-5
⇔5x=80
⇔x=16
phương trình có 1 nghiệm:x=16
Ta có: 2x+5=60-(3x-25)
\(\Leftrightarrow2x+5=60-3x+25\)
\(\Leftrightarrow2x+5=-3x+85\)
\(\Leftrightarrow2x+3x=85-5\)
\(\Leftrightarrow5x=80\)
hay x=16
Vậy: x=16
