Tìm x biết:
5x + 5.2 - ( 32 +16.3 : 6 -15) = 0
\(\Leftrightarrow\)\(5x+10-25=0\)
\(\Leftrightarrow\)\(5x=15\)
\(\Leftrightarrow\)\(x=\frac{15}{5}=3\)
a)460+85.4=(x+200).4
b)x+5.2-(32+16.3:16-15)=0
a) 460 + 85 * 4 = ( x + 200 ) * 4
460 + 340 = ( x + 200 ) * 4
800 = ( x + 200 ) * 4
x + 200 = 200
x = 0
b) x + 5 * 2 - ( 32 + 16 * 3 : 16 - 15 ) = 0
x + 10 - ( 32 + 3 - 15 ) 0
x + 10 - 20 = 0
x - 10 = 0
x = 10
a) \(460+85.4=\left(x+200\right).4\)
\(\Rightarrow460+340=4x+800\)
\(\Rightarrow-4x=800-460-340\)
\(\Rightarrow-4x=0\)
\(\Rightarrow x=0\)
Vậy x = 0
b) \(x+5.2-\left(32+16.3:16-15\right)=0\)
\(\Rightarrow x+10-\left(32+3-15\right)=0\)
\(\Rightarrow x+10-20=0\)
\(\Rightarrow x-10=0\)
\(\Rightarrow x=10\)
Vậy x = 10
a, \(460+85.4=\left(x+200\right)4\)
\(460+340=\left(x+200\right)4\)
\(800=\left(x+200\right)4\)
\(\Leftrightarrow x+200=\frac{800}{4}\)
\(\Leftrightarrow x+200=200\)
\(\Rightarrow x=200-200\)
\(\Rightarrow x=0\)
Vậy \(x=0\)
