x.1,2-3,45=4,68
x.1,2=4,68+3,45

\(x\times1,2+3,14\times x=1234\)
\(x\times\left(1,2+3,14\right)=1234\)
\(x\times4,34=1234\)
\(x=1234:4,34\)
\(x=284,3317972\)
Xx1,2 + 3,14xX = 1234
Xx(1,2 + 3.,14) = 1234
Xx4,34 = 1234
x = 1234 : 4,34
bn ơi xem lại xem có viết nhầm đề bài ko

X x 2+X x 1/6 =8/5
=> X x (2+1/6)=8/5
=> X x 13/6=8/5
=> X =8/5:13/6
=> X =48/65

\(x\times1,2+1,2\times3,8+x=12\)
\(x\times1,2+4,56+x=12\)
\(x\times\left(1,2+1\right)=12-4,56\)
\(x\times2,2=7,44\)
\(x=7,44:2,2=\frac{186}{55}\)

Có chs nhưng ít khi chs lắm :)))

Xx\(\frac{1}{4}\)+Xx\(\frac{1}{5}\)+Xx2=19,6
XxXxX=19,6:2:\(\frac{1}{5}\):\(\frac{1}{4}\)
Xx3=196
X=196:3
X=\(\frac{196}{3}\)
nhé bạn
\(x.\frac{1}{4}+x.\frac{1}{5}+x.2=19.6\)
\(x.\left(\frac{1}{4}+\frac{1}{5}+2\right)=19,6\)
\(x.2,45=19,6\)
\(x=19,6:2,45\)
\(x=8\)

\(x+x\cdot1,2+x\cdot1,8=4,92\)
\(x\cdot\left(1+1,2+1,8\right)=4,92\)
\(x\cdot4=4,92\)
\(x=1,23\)

a)\(\frac{5}{9}\times x-1=\frac{8}{9}\)
\(\frac{5}{9}\times x=\frac{8}{9}+1\)
\(\frac{5}{9}\times x=\frac{17}{9}\)
\(x=\frac{17}{9}:\frac{5}{9}\)
\(x=\frac{17}{5}\)

mình vừa trả lời bạn này xong, cậu vô xem nhé!!!
x*1,2+x*1,8=45
x*(1,2+1,8)=45
x* 3=45
x= 45:3
x=15
k dung cho mik nha!>-<
