thank you Nguyen Thanh Van

là so sánh à

o\uk, mi nek

\(\left(125\%+3\frac{3}{4}\right)\times\left(x-2\right)=25\)

=>\(\left(\frac{5}{4}+\frac{15}{4}\right)\times\left(x-2\right)=25\)

=>\(\frac{20}{4}\times\left(x-2\right)=25\)

=>\(5\times\left(x-2\right)=25\)

=>\(x-2=25:5\)

=>x-2=5

=>x=5+2

=>x=7

\(1+2+3+4=3+7=10\)
