帮我解一个简单的方程

(8x+7)*6/5+2x=13
6(8x+7)+10x=65
58x+42=65
58x=23
x=23/58

(8x+7)*6/5+2x=13
=>48x+42+10x=65=>x=23/58

解：8*6/5x+7*6/5+2x=13
9.6x+8.4+2x=13
11.6x=13-8.4
11.6x=4.6
x=23/58

(8x+7)*6/5+2x=13
(8x+7)*6+10x=65
48x+42+10x=65
58x+42-65=0
58x-23=0
x=23/58

(8x+7)*6/5+2x=13 他们的等号没对齐！
(8x+7)*6+10x=65
48x+42+10x=65
58x+42-65=0
58x-23=0
x=23/58
