5x+5x+1=150
<=> 5x+5x+1= 25 + 125
=> 5x+5x+1=52 + 53
=> x = 2
5x +5x+1=150
5x+5x+1 =25+125
5x+5x+1=52+53
=>x=2
Vậy x=2
5xx+1+5x=150
Tìm x
12(x – 1) = 0
45 + 5(x – 3) = 70
3.x – 18 : 2 = 12
5x + 2x = 62 - 50
5x + x = 150 : 2 + 3
a) 5x + 2x = 62 - 50
b) 5x + x = 150 : 2 + 3
c) 6x + x = 511 : 59 + 31
d) 5x + 3x = 36 : 33.4 + 12
4x + 2x = 68 – 219 : 216
Tìm x :
\(\frac{1}{1.6}+\frac{1}{6.11}+\frac{1}{11.16}+..+\frac{1}{\left(5x+1\right)\left(5x+6\right)}=\frac{10}{41}\)
5x+1+5x=150
tìm x
d) \(\frac{5}{1.6}+\frac{5}{6.11}+\frac{5}{11.16}+...+\frac{5}{\left(5x+1\right)\left(5x+6\right)}=\frac{2005}{2006}\)
a,4.(x-3)=7^2-1^3
b,5x+x=150/2+3
1. 5x + x = 39 - 3 mũ 11 : 3 mũ 9.
2. 5x + x = 150 : 2 + 3.
3. 7x - x = 5 mũ 21 : 5 mũ 19 + 3 . 2 mũ 2 - 1
4. 6x + x = 5 mũ 11 : 5 mũ 9 + 3
5x+x=150:2+3
g) 5x+x=150:2+3
