8x-6=7.2+ 5x解方程:8x-6=7.2+5x 20yuan
8x-6=7.2+ 5x
解方程:8x-6=7.2+5x 20yuan

8x-6=7.2+ 5x解方程:8x-6=7.2+5x 20yuan
8x-6=7.2+5x
x=6+7.2/(8x-5x)
x=13.2/3
x=4.4

3x=13.2
x=4.4

3x = 13.2
x=4.4

8x-6=7.2+5x
即 3x=13.2 (5x右移,-6左移)
x=4.4

8x-5x=7.2+6
3x=13.2
X=4.4

8x-6=7.2+5x
3x=13.2
x=4.4

8x-6=7.2+5x
8x-5x=7.2+6
3x=13.2
x=4.4

8x-5x=7.2+6
3x=13.2
x=4.4

3x=13.2
x=4.4
