tìm x
\(23-x=12\)
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:
x - 2 3 = 1 2
x - 2 3 = 1 2 x = 1 2 + 2 3 x = 7 6 = 1 1 6
tìm x biết 720:(x-17)=12 ; (-7)2.(-23+x)=(-49).(-23+13)
a) 720: ( x - 17) = 12
x-17 = 60
x = 77
b) (-7)^2 (-23+x) = (-49)(-23 + 13)
14(-23+x) = 490
-23 + x = 35
x = 58
Tìm x: 1 3 + 2 3 x x = 5 3 ÷ 1 2
Tìm x, biết : x - 1 2 = - 2 3
tìm x : 12 x X + X x 23 =1645
\(12\times x+x\times23=1645\)
\(x\times\left(12+23\right)=1645\)
\(x\times35=1645\)
\(x=1645:35=47\)
12 x X + X x 23 = 1645
X x ( 12 + 23 ) = 1645
X x 35 = 1645
X = 1645 : 35
X = 47
Tick nhé
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
