解方程2(x-2.6)=8 5(x+1.5)=17.5 8(X-6.2)=41.6 (x-3)÷2+7.5
解方程
2(x-2.6)=8 5(x+1.5)=17.5 8(X-6.2)=41.6 (x-3)÷2+7.5

解方程2(x-2.6)=8 5(x+1.5)=17.5 8(X-6.2)=41.6 (x-3)÷2+7.5
2(x - 2.6)= 8 5(x + 1.5) = 17.5 8(X - 6.2)= 41.6 (x - 3)÷ 2 + 7.5
2x - 5.2 = 8 5x - 7.5 = 17.5 8x - 49.6 = 41.6 ?
2x = 8 + 5.2 5x = 17.5 + 7.5 8x = 41.6 + 49.6
2x = 13.2 5x = 25 8x = 91.2
x = 6.6 x = 5 x = 11.4
