5(x+1.5)=17.52(x-2.6)=88(x-6.2)=41.6(x-3)÷2=7.5x+2.4x=5.15(x+1.5)=17.52(x-2.6)=88(x-6.2)=41.6(x-3)÷2

5(x+1.5)= 17.5 2(x-2.6)= 8 8(x-6.2)= 41.6(x-3)÷2 = 7.5 x+2.4x = 5.1
5(x+1.5)= 17.5 2(x-2.6)= 8 8(x-6.2)= 41.6
(x-3)÷2 = 7.5 x+2.4x = 5.1

5(x+1.5)= 17.5 2(x-2.6)= 8 8(x-6.2)= 41.6(x-3)÷2 = 7.5 x+2.4x = 5.1
(x-3)÷2 = 7.5
(x-3)=7.5乘2
x=15+3
x=18
x+2.4x = 5.1
3.4x=5.1
x=1.5
