tìm x : 12 x X + X x 23 =1645
tìm x biết (x+12) / 25 + (x+13 ) /24+(X+14) /23=(X+25) /12+(X+24) /13+(X+23) /24
Tìm x
a) x + 1 2 = − 4 5
b) − 3 4 − x = 2 3
c) 2 3 5 + − 3 5 : x = − 2 3
a ) x = − 4 5 − 1 2 ⇔ x = − 13 10 b ) x = − 3 4 − 2 3 ⇔ x = − 17 12 c ) − 3 5 : x = − 2 3 − 2 3 5 ⇔ − 3 5 : x = − 49 15 ⇔ x = − 3 5 : − 49 15 ⇔ x = 9 49

Tìm x: 1 3 + 2 3 x x = 5 3 ÷ 1 2
Tìm x:
a . x - 1 4 = 5 3
x : 2 3 = 1 2
a. x - 1/4 = 5/3
x = 5/3 + 1/4
x = 23/12
b. x : 2/3 = 1/3
x = 1/2 x 2/3
x = 1/3
Tìm x
a , x - 1 4 = 5 3 b , x : 2 3 = 1 2
Tìm x
a , x - 1 2 = 2 7 b , x : 2 3 = 2 9
