15 + 4 (x - 2) = 95
4 (x - 2) = 95 - 15 = 80
x - 2 = 80 : 4 = 20
x = 20 + 2 = 22
15 +4. {x-2}=95
tìm x
15+4(x-2)=95
Tìm x
15+4.(x-2)=95
20-(x+14)=5
15+4(X-2)=95
24+3(5-X)=27
. 249 - 95 x 8 + 32 x 4
. ( 315 x 4 + 315 x 5 ) : 316
bài 19: tìm x
c) ( 34 - 2x ) . ( 2x - 6 ) = 0
d) ( 2019 - x ) . ( 3x - 12 ) 0
e) 57 . ( 9x - 27 ) = 0
f) 25 + ( 15 - x ) = 30
g) 43 - ( 24 - x ) = 20
h) 2 . ( x - 5 ) - 17 = 25
i) 3 . ( x + 7 ) - 15 = 27
j) 15 + 4 . ( x - 2 ) = 95
k) 20 - ( x + 14 ) = 5
l) 14 + 3 . ( 5 - x ) = 27
nhanh nha, mik tick cho, ccau trình bày dễ hiểu, ko cần ''hoặc''
x+5/95 + x+10/90 + x+15/85 + x+20/80=4
1) –45 + 5.(–2x) = 95
2) x.(12 + x).(71 – x) = 0
3) (x – 11).(x + 12).(–x – 13) = 0
4) |2.x – 15| = 7
5) –2.|x + 32| = –112
tim x
2x-3=7
3*(x+7)=15
24*3(5-x)=27
15+4*(x-2)=95
ai dung minh se tick cho
