TIM X
1. Tìm x, biết :
a. 1440: [120-(3x+9)] =120
b. 120+ [(999-9x):60].24 =480
c. (3x-48).6 =33.32+23.32 = 122
d. x10 = x
e. (2x-15)5 = (2x -15)3
f. 6.2x + 7.2x = 13.29
117x(36+62)-17x(62+36)
Tìm x biết 120+[(999-9x):60].24=480
Tìm xEN
a. 720 : [118- (2x + 10)]=60
b. 2840+ [(999 - 9x ) : 60 ] x 24 = 3200
c. ( 3x - 48 ) x 6 = 33 . 22 - 23 . 32
Tìm x
120+ [ (999-9x) /60 ]= 480/24
Tình bày ra nhé
tìm x
17x – ( -16x – 37) = 2x +
-2x –3. (x – 17) = 34 – 2(-x + 25
17x + 3. ( -16x – 37) = 2x + 43 - 4x
103 -57: [-2. (2x – 1)2 – (-9)0] = -106
3x – 32 > -5x + 1
15 + 4x < 2x – 145
-3. (2x + 5) -16 < -4. (3 – 2x)
-2x + 15 < 3x – 7 < 19 – x
x + (x+1) + (x+2) + (x+3) + .... + 13 + 14 = 14
25 + 24 + 23 +...+ x + (x - 2) + (x – 3) = 25
1/ (2x - 5) +17 =6
2/ 10 - 2(4 - 3x) = - 4
3/- 12 +3(- x + 7) = -18
4/ 24 :(3x - 2)= - 3
5/ - 45 :5.(- 3- 2x) = 3
tìm số nguyên x
-2x-(x-17)=34-(-x+25)
17x-(16x-37)=2x+43
-2x-3(x+17)=34-2(-x+25)
17x+3(16x-37)=2x+43-14x
-2x+15<3x-7<19-x
