解下列方程

6Χ+3.6=12 8Χ+25=57 0.8+3.6Χ=1.52 3.5-40%Χ=2.7

Χ=18 Χ= Χ÷14= Χ-Χ=

Χ-Χ= 1-Χ= 8Χ+= :Χ=

×Χ= Χ÷= Χ+Χ= Χ-Χ=

Χ = 15 Χ÷ = Χ÷=18     Χ+Χ=15

Χ×(1-)=3.6 -Χ= Χ+= 7Χ-=

Χ+2Χ= 5Χ-=     Χ-20%Χ=1 Χ+Χ=

×(+)= -Χ=   Χ÷= 7.2-2Χ=3.8

(6+3Χ)÷2=18 (Χ-0.4):8=3:2  6Χ+2Χ=56     12Χ÷3=16

8.8+4Χ=40 3Χ-0.5Χ=5 0.24Χ-1.8=4.2 3Χ+5×0.3=4.5
