(6x5:X)+15=4
30:X=4-15=-11
=>X=30:(-11)=-\(\frac{30}{11}\)
hihi, chúc bn hk tốt nha >,<
(6x5-x)2=676.tìm x
tìm x,biết
5-x-16=40+x
4x-10=15-x
15-x=4x-5
x-15=6+4x
-12+x=5x-20
7x-4=20+3x
5x-7=-21-2x
x+15=20-4x
17-x=7-6x
tim x biet [ 4x - 15 ] ^ 2016 = [ 4x - 15 ] ^ 2015
a) -12+x=5x-20
b) 4x-10=15-x
c) 7x-4=20+3x
d) 3x-6=5x+2
e) 5x-7=-21-2x
f) 15-x=4x-5
g) x+15=20-4x
tìm x biết:
a, 5x - 16 = 41 + x
b, 4x - 1 =15 - x
c, x - 15 = 6 + 4x
Tìm x
1) 5x - 16 = 40 + x
2) 4x - 10 = 15 - x
3) 3x - 6 = 5x + 2
4) 15 - x = 4x - 5
5) x - 15 = 6 + 4x
6) -12 + x = 5x - 20
7) 7x - 4 = 20 + 3x
8) 5x - 7 = -21 - 2x
9) x + 15 = 20 - 4x
10) 17 - x = 7 - 6x
Bài2: a)5x-16=40+x
b)4x-10=15-x
c) x+15=20-4x
d)17x=7-6x
câu 1: tìm x biết:
a, (4x-15)^2016=(4x-15)^2015
b,2^x+2^x+1+2^x+2+2^x+3-480=0
Tính
22+6x5=?
