a, x = 2
b, x = 0
mình đầu tiên k mình nha bạn
:))))
a) Xx(17+33)=100
Xx50=100
x=100:50=2
b)x+6=270:45=6
x=6-6=0
\(a.17x+33x=100\)
\(\left(17+33\right)x=100\)
\(50x=100\)
\(x=100:50\)
\(x=2\)
\(b.45\left(x+6\right)=270\)
\(\left(x+6\right)=270:45\)
\(\left(x+6\right)=6\)
\(x=6-6\)
\(x=0\)
a) 17x+33x=100
=>(17+33)x=100
=>50x=100

=>x=0
\(17x+33x=100\)
\(x\left(17+33\right)=100\)
\(x\cdot50=100\)
\(x=100:50\)
\(x=2\)
\(45\cdot\left(x+6\right)=270\)
\(x+6=270:45\)
\(x+6=6\)
\(x=6-6\)
\(x=0\)
a) 17x + 33x =100
(17 + 33) .x =100
50 * x =100
x= 100/50
x= 2
b) 45(x+6) = 270
x+6 = 6
x = 6-6
x = 0
chuc e luon hoc tot nha!
