tìm x biết
1) x=-1/2 + 3/4 2) x - 1/5 = 2/11 3) x - 5/6 = 16/42 + -8/56
4) x/5 = 5/6 + -19/30 5) |x| - 1/4 = 6/18 6)x = -1/2 +3/4
7) x/15 = 3/5 + -2/3 8)11/8 + 13/6 = 85/x 9) x - 7/8 = 13/12
10) x - -6/15 = 4/27 11) -\(\dfrac{-6}{12}\)+ x = 9/48 12) x - 4/6 = 5/25 + -7/15
16/ 1/2.x+1/6.x(x-2)=3/4-2.x
19/ 5/12.x+3=1/3-7/12.x
20/ 1/2.x+5/2=7/2.x-3/4
Mọi người giúp mình với mình đang cần gấp!!!
| 7 - 3/4 . x | - 3/2 = 1/1/2
5 - | x - 3 | = 5
| 7/2 - 42 | + 14 = 14
2/3 - | x + 2 | = 2
5/6 . | 3 - x | + 4 = 2
Giải giúp mình với
a,5^x+4-3×5^x+3=2×5^11
b,3×5^x+2+4×5^x-3=19×5^10
c,6×8^x-1+8^x-1=6×8^19+8^21
d,5×2^x+3×2^x+2=5×2^5+3×2^7
1) 17/6 - (x-7/6)=7/4
2) 3/35-(3/5-x)=2/7
3) 2x-3=x+1/2
4) 11/12-(2/5+x)-2/3
