88-2(5X-8)=40 帮我解方程!我急!

88-2(5X-8)=40 帮我解方程!我急!
88-2(5X-8)=40
2(5X-8)=88-44
2(5X-8)=36
5X-8=18
5X=18+8
X=26
X=26/5
X=5.2

82.21

88-2(5X-8)=40 ,88-10x+16=40,10x=64,x=6.4


88-10x+16=40
-10x=40-88-16
-x=-6.4
x=6.4

88-2(5X-8)=40
2(5X-8)=88-44
10x-16=36
10x=36+16
10x=52
X=5.2

88-2(5x-8)=40
解 86(5x-8)=40
(5x-8)=40+86=126
