Tìm x, biết:
a. 12 + x = 122
=> x=122-12
=> x= 110
b. | x | + 4 = 8
=> /x/=8-4
=> /x/=4
=> x={4;-4}
c. 3x - 5 . 32 = 32 . 4
=> 3x=32.(4+5)
=> 3x=32.32
=> 3x=34
=> x=4
a)
\(12+x=122\)
=> \(x=110\)
Vậy \(x=110\)
b)
\(\left|x\right|+4=8\)
\(\Rightarrow\left|x\right|=4\)
\(\Rightarrow\left[\begin{array}{nghiempt}x=4\\x=-4\end{array}\right.\)
Vậy x=4 ; x = - 4
c)
\(3^x-5.3^2=4.3^2\)
\(\Rightarrow3^x=3^2\left(4+5\right)\)
\(\Rightarrow3^x=3^4\)
=> x=4
Vậy x=4

a)x2 +x =0
x(x+1)=0
* x=0
* x+1=0
x=0-1
x=-1
Vậy x=0 hoặc x=-1
2.(x-1) +3(x-2) =x-4
2x-2+3x-6=x-4
x+3x-x=-4+2+6
3x=4
x=\(\frac{4}{3}\)
a,
x2 +x =0
\(\orbr{\begin{cases}x^2=0\\x=0\end{cases}}\)
Vậy x= 0
b,2.(x-1) +3(x-2) =x-4
2x - 2 + 3x - 6 = x - 4
2x + 3x - x = -4 +6 + 2
4x = 0
Vậy x = 0
Take it easy:
2 X 2 = 42 with 4 = 2 X 2 and 2 = 2 X 2 - 2
2 X 4 = 86 with 8 = 2 X 4 and 6 = 2 X 4 - 2
6 X 3 = 1812 with 18 = 6 X 3 and 12 = 6 X 3 - 6
...
So 7 X 2 = 147 with 14 = 7 X 2 and 7 = 7 X 2 - 7
7 X 2 = 14
