Question

6道简单不一样的解方程,要把方程解出来

Answer 1

x+5=6

x=6-5

x=1

2x+3x=3+2

5x=5

x=1

5x+6=6x+5

5x-6x=5-6

-x=-1

x=1

x/2+x/3=1/2+1/3

5x/6=5/6

x=1

0.75x+10=0.25x+10.5

0.75x-0.25x=10.5-10

0.5x=0.5

x=1

200(100+100x)=100(100x+300)

2(100+100x)=100x+300

200+200x=100x+300

200x-100x=300-200

100x=100

x=1
