tìm x biết: (x+1)+(x+4)+(x+7)+(x+10)=62
tìm x biết : ( x + 1 ) + ( x + 4 ) + ( x + 7 ) + ( x + 10 ) = 62
(x+1)+(x+4)+(x+7)+(x+10)=62
=>4x+22=62
=>4x=62-22
=>4x=40
=>x=10
t tôi nha bn
( x + 1 ) + ( x + 4 ) + ( x + 7 ) + ( x + 10 ) = 62
4x+ (1+4+7+10)=62
4x+22=62
4x=62-22
4x=40
x=40:4
x=10
1. tìm x
(x+1)+(x+4)+(x+7)+(x+10)=62
(x+1)+(x+4)+(x+7)+(x+10)=62
( x + x + x + x ) + ( 1 + 4 + 7 + 10 ) = 62
4x + 22 = 62
4x = 62 - 22
4x = 40
x = 40 : 4
x = 10
(x + 1) + (x + 4) + (x + 7) + (x + 10) = 62
x + 1 + x + 4 + x + 7 + x + 10 = 62
4x + 22 = 62
4x = 40
=> x = 40 / 10 = 4

tìm x biết: a) [0,(37)+0,(62)]x=10
b)0,(12):1,(6)=x:0.(4)
tìm x biết: a) [0,(37)+0,(62)]x=10
b)0,(12):1,(6)=x:0.(4)
a: \(\Leftrightarrow x\cdot\left(\dfrac{37}{99}+\dfrac{62}{99}\right)=10\)
=>x=10
b: \(\Leftrightarrow x:\dfrac{4}{9}=\dfrac{4}{33}:\dfrac{5}{3}=\dfrac{4}{33}\cdot\dfrac{3}{5}=\dfrac{4}{55}\)
