Ta có : \(\left(x+1\right)+\left(x+3\right)+\left(x+5\right)+\left(x+7\right)=32\)
\(\Leftrightarrow x+x+x+x+1+3+5+7=32\)
\(\Leftrightarrow4x+16=32\Leftrightarrow4x=16\Leftrightarrow x=4.\)
\(\left(x+1\right)+\left(x+3\right)+\left(x+5\right)+\left(x+7\right)=32\)
\(\left(x+x+x+x\right)+\left(1+3+5+7\right)=32\)
\(4x+16=32\)
\(4x=16\)
\(\Leftrightarrow x=4\)
(x+1)+(x+3)+(x+5)+(x+7)=32
=> x+1+x+3+x+5+x+7 =32
=> 4x + 16 = 32
=> 4x = 32-16
=> 4x = 16
=> x = 4
Vậy x=4
(x + 1) + (x + 3) + (x + 5) + (x + 7) = 32
=> (x + x + x + x ) + (1 + 3 + 5 + 7) = 32
=> 4x + 16 = 32
=> 4x = 32 - 16
=> 4x = 16
=> x = 16 : 4
=> x = 4
Vậy x = 4
\(\left(x+1\right)+\left(x+3\right)+\left(x+5\right)+\left(x+7\right)=32\)\(32\)
\(\left(x+x+x+x\right)+\left(1+3+5+7\right)=32\)
\(4x+16=32\)\(4x=16\)
\(=4\)
( x + 1 ) + ( x + 3 ) + ( x + 5 ) + ( x + 7 ) = 32
=> ( x + x + x + x ) + ( 1 + 3 + 5 + 7 ) = 32
=> 4x + 16 = 32
=> 4x = 32 - 16
=> 4x = 16
=> x = 16 : 4 = 4
( x + 1 ) + ( x + 3 ) + ( x + 5 ) + ( x + 7 ) = 32
( x + x + x + x ) + ( 1 + 3 + 5 + 7 ) = 32
4x + 16 = 32
4x = 32 - 16
x = 16 : 4
x = 4
Vậy x = 4
