gì vậy bạn

Đáy bé thửa ruộng hình thang là:

\(90.\frac23=60\left(m\right)\)

Chiều cao thửa ruộng hình thang là:

\(60-20=40\left(m\right)\)

Diện tích thửa ruộng hình thang là:

\(\frac{\left(90+60\right).20}{2}=1500\left(m^2\right)\)

Số thóc thửa ruộng đã thu được là:

\(1500:100.62,8=942\left(\operatorname{kg}\right)\)

\(60-3\left(x:2-2\right)=51\)

\(3\left(x:2-2\right)=60-51\)

\(3\left(x:2-2\right)=9\)

\(x:2-2=9:3\)

\(x:2-2=3\)

\(x:2=3+2\)

\(x:2=5\)

\(x=5.2\)

\(x=10\)

\(Vậy\) \(x=10\)
