108-3(x+4)=23
3(x+4)=108-23
3(x+4)=85
x+4=85:3
x+4=\(\frac{85}{3}\)
⇒x=\(\frac{85}{3}\)-4=\(\frac{73}{3}\)
108-3(x+4)=23
3(x+4)=108-23
3(x+4)=85
x+4 = 85 : 3
x+4 = 28,333....
x = 28,333....- 4
x = 24,333...
108-3(x+4)=23
3(x+4)=108-23
3(x+4)=85
x+4=85:3
x+4=28,333
x=28,333-4
x=24,333
108 - 3(x + 4) = 23
3(x + 4) = 108 - 23
3(x + 4) = 85
x + 4 = 85 : 3
x + 4 = \(\frac{85}{3}\)
x = \(\frac{85}{3}\) - 4
x = \(\frac{73}{3}\)
giúp mình với nha!cảm ơn nhiều
